Abstract: Abstract We report results from a study of B ± → DK ± decays followed by D decaying to the CP-even final state K + K − and CP-odd final state K S 0 π 0 $$ {K}_S^0{\pi}^0 $$ , where D is an admixture of D 0 and D ¯ 0 $$ {\overline{D}}^0 $$ states. These decays are sensitive to the Cabibbo-Kobayashi-Maskawa unitarity-triangle angle ϕ 3. The results are based on a combined analysis of the final data set of 772 × 106 B B ¯ $$ B\overline{B} $$ pairs collected by the Belle experiment and a data set of 198 × 106 B B ¯ $$ B\overline{B} $$ pairs collected by the Belle II experiment, both in electron-positron collisions at the Υ(4S) resonance. We measure the CP asymmetries to be A $$ \mathcal{A} $$ CP+ = (+12.5 ± 5.8 ± 1.4)% and A $$ \mathcal{A} $$ CP− = (−16.7 ± 5.7 ± 0.6)%, and the ratios of branching fractions to be R $$ \mathcal{R} $$ CP+ = 1.164 ± 0.081 ± 0.036 and R $$ \mathcal{R} $$ CP− = 1.151 ± 0.074 ± 0.019. The first contribution to the uncertainties is statistical, and the second is systematic. The asymmetries A $$ \mathcal{A} $$ CP+ and A $$ \mathcal{A} $$ CP− have similar magnitudes and opposite signs; their difference corresponds to 3.5 standard deviations. From these values we calculate 68.3% confidence intervals of (8.5 ° < ϕ 3 < 16.5 ° ) or (84.5 ° < ϕ 3 < 95.5 ° ) or (163.3 ° < ϕ 3 < 171.5 ° ) and 0.321 < r B < 0.465.

Abstract: Abstract We report the measurement of the two-photon decay width of χ c2(1P) in two-photon processes at the Belle experiment. We analyze the process γγ → χ c2(1P) → J/ψγ, J/ψ → ℓ + ℓ − (ℓ = e or μ) using a data sample of 971 fb −1 collected with the Belle detector at the KEKB e + e − collider. In this analysis, the product of the two-photon decay width of χ c2(1P) and the branching fraction is determined to be Γ γγ χ c 2 1 P B χ c 2 1 P → J / ψγ B J / ψ → ℓ + ℓ − = 14.8 ± 0.3 stat . ± 0.7 syst . $$ {\Gamma}_{\gamma \gamma}\left({\chi}_{c2}(1P)\right)\mathcal{B}\left({\chi}_{c2}(1P)\to J/\psi \gamma \right)\mathcal{B}\left(J/\psi \to {\ell}^{+}{\ell}^{-}\right)=14.8\pm 0.3\left(\textrm{stat}.\right)\pm 0.7\left(\textrm{syst}.\right) $$ eV, which corresponds to Γ γγ (χ c2(1P)) = 653 ± 13(stat.) ± 31(syst.) ± 17(B.R.) eV, where the third uncertainty is from B $$ \mathcal{B} $$ (χ c2(1P) → J/ψγ) and B $$ \mathcal{B} $$ (J/ψ → ℓ + ℓ − ).

Abstract: Abstract We report a measurement of the electric dipole moment of the τ lepton (dτ) using an 833 fb −1 data sample collected near the Υ(4S) resonance, with the Belle detector at the KEKB asymmetric-energy e + e − collider. Using an optimal observable method, we obtain the real and imaginary parts of d τ as Re(d τ ) = (−0.62 ± 0.63) × 10 −17 ecm and Im(d τ ) = (−0.40 ± 0.32) × 10 −17 ecm, respectively. These results are consistent with null electric dipole moment at the present level of experimental sensitivity and improve the sensitivity by about a factor of three.

Abstract: Abstract Charged lepton flavor violation is forbidden in the Standard Model but possible in several new physics scenarios. In many of these models, the radiative decays τ ± → ℓ ± γ (ℓ = e, μ) are predicted to have a sizeable probability, making them particularly interesting channels to search at various experiments. An updated search via τ ± → ℓ ± γ using full data of the Belle experiment, corresponding to an integrated luminosity of 988 fb −1, is reported for charged lepton flavor violation. No significant excess over background predictions from the Standard Model is observed, and the upper limits on the branching fractions, B $$ \mathcal{B} $$ (τ ± → μ ± γ) ≤ 4.2 × 10 −8 and B $$ \mathcal{B} $$ (τ ± → e ± γ) ≤ 5.6 × 10 −8, are set at 90% confidence level.

Abstract: Abstract Using a data sample of 980 fb −1 collected with the Belle detector at the KEKB asymmetric-energy e + e − collider, we study the processes of Ξ c 0 → Λ K ¯ ∗ 0 $$ {\Xi}_c^0\to \Lambda {\overline{K}}^{\ast 0} $$ , Ξ c 0 → Σ 0 K ¯ ∗ 0 $$ {\Xi}_c^0\to {\Sigma}^0{\overline{K}}^{\ast 0} $$ , and Ξ c 0 → Σ + K ∗ − $$ {\Xi}_c^0\to {\Sigma}^{+}{K}^{\ast -} $$ for the first time. The relative branching ratios to the normalization mode of Ξ c 0 → Ξ − π + $$ {\Xi}_c^0\to {\Xi}^{-}{\pi}^{+} $$ are measured to be B Ξ c 0 → Λ K ¯ ∗ 0 / B Ξ c 0 → Ξ − π + = 0.18 ± 0.02 stat . ± 0.01 syst . , B Ξ c 0 → Σ 0 K ¯ ∗ 0 / B Ξ c 0 → Ξ − π + = 0.69 ± 0.03 stat . ± 0.03 syst . , B Ξ c 0 → Σ + K ∗ − / B Ξ c 0 → Ξ − π + = 0.34 ± 0.06 stat . ± 0.02 syst . , $$ {\displaystyle \begin{array}{c}\mathcal{B}\left({\Xi}_c^0\to \Lambda {\overline{K}}^{\ast 0}\right)/\mathcal{B}\left({\Xi}_c^0\to {\Xi}^{-}{\pi}^{+}\right)=0.18\pm 0.02\left(\mathrm{stat}.\right)\pm 0.01\left(\mathrm{syst}.\right),\\ {}\mathcal{B}\left({\Xi}_c^0\to {\Sigma}^0{\overline{K}}^{\ast 0}\right)/\mathcal{B}\left({\Xi}_c^0\to {\Xi}^{-}{\pi}^{+}\right)=0.69\pm 0.03\left(\mathrm{stat}.\right)\pm 0.03\left(\mathrm{syst}.\right),\\ {}\mathcal{B}\left({\Xi}_c^0\to {\Sigma}^{+}{K}^{\ast -}\right)/\mathcal{B}\left({\Xi}_c^0\to {\Xi}^{-}{\pi}^{+}\right)=0.34\pm 0.06\left(\mathrm{stat}.\right)\pm 0.02\left(\mathrm{syst}.\right),\end{array}} $$ where the uncertainties are statistical and systematic, respectively.

Abstract: Abstract We report the first measurement of the exclusive cross sections e + e − → B B ¯ $$ B\overline{B} $$ , e + e − → B B ¯ ∗ $$ B{\overline{B}}^{\ast } $$ , and e + e − → B ∗ B ¯ ∗ $$ {B}^{\ast }{\overline{B}}^{\ast } $$ in the energy range from 10.63 GeV to 11.02 GeV. The B mesons are fully reconstructed in a large number of hadronic final states and the three channels are identified using a beam-constrained-mass variable. The shapes of the exclusive cross sections show oscillatory behavior with several maxima and minima. The results are obtained using data collected by the Belle experiment at the KEKB asymmetric-energy e + e − collider.

Abstract: Abstract We present measurements of the branching fractions for the decays B → Kμ + μ − and B → Ke + e − , and their ratio (R K ), using a data sample of 711 fb −1 that contains 772 × 106 B B ¯ $$ B\overline{B} $$ events. The data were collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e + e − collider. The ratio R K is measured in five bins of dilepton invariant-mass-squared (q 2): q 2 ∈ (0.1, 4.0), (4.00, 8.12), (1.0, 6.0), (10.2, 12.8) and (> 14.18) GeV2 /c 4, along with the whole q 2 region. The R K value for q 2 ∈ (1.0, 6.0) GeV2 /c 4 is 1.03 − 0.24 + 0.28 $$ {1.03}_{-0.24}^{+0.28} $$ ± 0.01. The first and second uncertainties listed are statistical and systematic, respectively. All results for R K are consistent with Standard Model predictions. We also measure CP-averaged isospin asymmetries in the same q 2 bins. The results are consistent with a null asymmetry, with the largest difference of 2.6 standard deviations occurring for the q 2 ∈ (1.0, 6.0) GeV2 /c 4 bin in the mode with muon final states. The measured differential branching fractions, d ℬ $$ d\mathrm{\mathcal{B}} $$ /dq 2, are consistent with theoretical predictions for charged B decays, while the corresponding values are below the expectations for neutral B decays. We have also searched for lepton-flavor-violating B → Kμ ± e ∓ decays and set 90% confidence-level upper limits on the branching fraction in the range of 10 −8 for B + → K + μ ± e ∓, and B 0 → K 0 μ ± e ∓ modes.

Abstract: Abstract The first dedicated search for the η c2(1D) is carried out using the decays B + → η c2(1D)K +, B 0 → η c2(1D) K S 0 $$ {K}_S^0 $$ , B 0 → η c2(1D)π − K +, and B + → η c2(1D)π + K S 0 $$ {K}_S^0 $$ with η c2(1D) → h c γ. No significant signal is found. For the η c2(1D) mass range between 3795 and 3845 MeV/c 2, the branching-fraction upper limits are determined to be ℬ(B + → η c2(1D)K +) × ℬ(η c2(1D) → h c γ) < 3.7 × 10 −5, ℬ(B 0 → η c2(1D)K 0) × ℬ(η c2(1D) → h c γ) < 3.5 × 10 −5, ℬ(B 0 → η c2(1D)π − K +) × ℬ(η c2(1D) → h c γ) < 1.0 × 10 −4, and ℬ(B + → η c2(1D)π + K S 0 $$ {K}_S^0 $$ ) × ℬ(η c2(1D) → h c γ) < 1.1 × 10 −4 at 90% C.L. The analysis is based on the 711 fb −1 data sample collected on the ϒ(4S) resonance by the Belle detector, which operated at the KEKB asymmetric-energy e + e − collider.

Abstract: Abstract We study bottomonium production in association with an $$\eta $$ η meson in $$e^+e^-$$ e+e- annihilations near the $$\varUpsilon (5S)$$ Υ(5S) , at a centre-of-mass energy of $$\sqrt{s}=10.866$$ s=10.866 GeV. The results are based on the 121.4 fb$$^{-1}$$ -1 data sample collected by the Belle experiment at the asymmetric-energy KEKB collider. Only the $$\eta $$ η meson is reconstructed and the missing-mass spectrum of $$\eta $$ η candidates is investigated. We observe the $$e^+e^-\rightarrow \eta \varUpsilon _J(1D)$$ e+e-→ηΥJ(1D) process and find evidence for the $$e^+e^-\rightarrow \eta \varUpsilon (2S)$$ e+e-→ηΥ(2S) process, while no significant signals of $$\varUpsilon (1S)$$ Υ(1S) , $$h_b(1P)$$ hb(1P) , nor $$h_b(2P)$$ hb(2P) are found. Cross sections for the studied processes are reported.

19. First beam loss measurements in the SuperKEKB positron ring using the fast luminosity monitor diamond sensors

Abstract: SuperKEKB is a very high luminosity e^{+}e^{−} collider consisting of a low energy ring (LER) of positrons of 4 GeV and a high energy ring (HER) of electrons of 7 GeV. The high luminosity will be achieved thanks to the nanobeam scheme, where very strongly focused beams (σ_{y}=60 nm) will collide at a large crossing angle of 83 mrad. To maintain high luminosity operation, fast luminosity monitoring is essential in the presence of dynamic instabilities, for feedback and optimization. Fast luminosity monitors consisting of a single crystalline diamond sensor (LAL), a Cherenkov and scintillator detector (KEK) were placed in both rings downstream of the IP (interaction point) to measure the signal from the radiative Bhabha process at zero photon scattering angle (σ≈200 mbarn). During single beam commissioning of SuperKEKB, the fast luminosity monitors were used as beam loss monitors to measure the single beam losses (beam-gas bremsstrahlung, Touschek scattering, Coulomb scattering). In this paper, a detailed description of the experimental setup, the data acquisition scheme, the data analysis and the comparison with the simulation for the diamond sensors, will be reported.

25. Measurement of coherent beam-beam tune shift under crabbing collision at KEKB

Author: T. Ieiri, Y. Ohnishi, M. Tobiyama, and S. Uehara
Subjects: Nuclear and particle physics. Atomic energy. Radioactivity, QC770-798
Abstract: Effective head-on collision and improvement in specific luminosity were established by the installation of crab cavities in KEKB. Tune spectra of a colliding bunch in a crabbing collision were observed by using a spectrum analyzer. The beam-beam spectrum showed strong nonlinear resonance. By taking into account this nonlinearity, the coherent beam-beam tune shift was measured as a function of the bunch current. The vertical beam-beam parameter estimated from the coherent beam-beam tune shift was found to agree with that observed by using a bunch-by-bunch luminosity monitor. The estimated vertical beam-beam parameter is saturated at approximately 0.05; this value is the beam-beam limit. Further, the bunch current corresponding to the beam-beam limit was found to be considerably lower than that used in usual operations. The horizontal beam-beam parameter was not saturated over 0.15. The horizontal beam-beam parameter estimated from the coherent beam-beam tune shift approximately agrees with a calculated beam-beam parameter considering the dynamic beam-beam effect.

Abstract: Pearlite refining is one of the most used methods to increase the strength of cast irons, and it can be achieved using different strategies. In this work, three strategies to obtain pearlite refining were applied to a given hypoeutectic gray cast iron centrifuged in a coated steel mold: (1) increasing the Cu, Mo and Cr contents; (2) intensifying the cooling rate of the metallic mold; and (3) cooling of the cast iron with forced air. Strategies 2 and 3 aimed to increase the cooling rate during the eutectoid reaction. Then, four experiments were conducted: a reference experiment and other three applying separately the strategies above. Materials samples were characterized by optical metallography, chemical analyses, microhardness, pearlite interlamellar spacing measurements and tensile tests. The metallographic examination did not show any important change in the graphite morphology. The pearlite interlamellar spacing and microhardness were computed as distribution curves from at least thirty measurements in the materials matrices. These curves showed a decrease in pearlite interlamellar spacing and an increase in pearlite microhardness for the three materials in which the pearlite refining strategies were applied as compared to the reference material. The mean pearlite interlamellar spacings were reduced from 0.10 μm for the reference material to 0.07 μm, 0.08 μm and 0.08 μm for the materials in which strategies 1, 2 and 3 were applied, respectively. The UTS increased from 378 MPa for the reference material to 423 MPa, 418 MPa and 390 MPa for the strategies 1, 2 and 3, respectively.

Abstract: Introduction Radical cystectomy (RC) is still gold standard for muscle invasive bladder cancer (MIBC). Whereas, bladder-sparing therapy with transurethral resection of bladder tumor (TUR) and chemoradiation therapy (CRT) has been recognized as an alternative treatment to RC for selected patients with MIBC. We have developed and implemented tetra-modality bladder-sparing therapy (TeMT) incorporating partial cystectomy (PC) in addition to maximal TUR and induction CRT to overcome local recurrence after bladder-sparing therapy (Kageyama et al. Am J Clin Oncol 2003, Koga et al. BJU Int 2012, Kijima et al. BJU Int 2019). There are few studies on erectile and ejaculatory functions after bladder-sparing therapy. Objective To cross-sectionally survey erectile and ejaculatory functions after TeMT in patients with MIBC. Methods Of the total 117 male patients with MIBC who completed TeMT between 2006 and 2019, 70 patients were set as the target to distribute the questionnaires after excluding patients lost to follow up as of February 2020, patients with local recurrence of MIBC or additional prostate cancer treatment. Erectile function was assessed using the International Index of Erectile Function short form (IIEF-5), and ejaculatory function using Male Sexual Health Questionnaire Ejaculatory Dysfunction short form (MSHQ-EjD-SF). Attending physicians handed the questionnaires to the patients at the first regular outpatient visit after February 2020 and had the patients complete them outside the office. Results Of 44 patients received the questionnaires between February and August 2020, 35 completed the questionnaires. The median age (range) of the eligible patients was 70 (50-87) years old, and the median time from the date of PC to the date of response was 5.2 (0.35-14) years. The results of IIEF-5 showed that 3 (9%) had no erectile dysfunction (ED) (22-25 points), 9 (26%) had mild ED (17-21 points), 4 (11%) had mild to moderate ED (12-16 points), 4 (11%) had moderate ED (8-11 points), and 15 (43%) had severe ED (5-7 points). Based on the results of MSHQ-EjD-SF, 23 patients (66%) responded that they could ejaculate. Of those, 5 patients (14%) scored 4 or higher on all questions 1-3 of MSHQ-EjD-SF, suggesting that they did not have ejaculatory dysfunction. Conclusions Preservation of erectile and ejaculatory functions was observed in MIBC patients treated with bladder-sparing therapy. Along with that of lower urinary tract function, preservation of male sexual function in bladder-sparing therapy, especially ejaculatory function which is inevitably lost by RC, is considered to be an advantage over RC.

Abstract: We report results from a study of the spin and parity of $\Xi_{c}(2970)^+$ using a $980~\mathrm{fb^{-1}}$ data sample collected by the Belle detector at the KEKB asymmetric-energy $e^{+}e^{-}$ collider. The decay angle distributions in the chain $\Xi_{c}(2970)^+ \to \Xi_c(2645)^{0}\pi^{+} \to \Xi_c^{+}\pi^{-}\pi^{+}$ are analyzed to determine the spin of this charmed-strange baryon. The angular distributions strongly favor the $\Xi_{c}(2970)^+$ spin $J =1/2$ over $3/2$ or $5/2$, under an assumption that the lowest partial wave dominates in the decay. We also measure the ratio of $\Xi_{c}(2970)^+$ decay branching fractions $R={\mathcal{B}[ \Xi_{c}(2970)^+ \to \Xi_c(2645)^{0}\pi^{+} ]} / { \mathcal{B}[ \Xi_{c}(2970)^+ \to \Xi_c^{\prime0}\pi^{+} ]} =1.67 \pm 0.29\mathrm{(stat.)}^{ +0.15}_{ -0.09}\mathrm{(syst.)} \pm 0.25\mathrm{(IS)}$, where the last uncertainty is due to possible isospin-symmetry-breaking effects. This $R$ value favors the spin-parity $J^P=1/2^+$ with the spin of the light-quark degrees of freedom $s_{l}=0$. This is the first determination of the spin and parity of a charmed-strange baryon.

Abstract: We report measurements of the branching fractions of singly Cabibbo-suppressed decays Λc+→pη and Λc+→pπ0 using the full Belle data sample corresponding to an integrated luminosity of 980.6 fb-1. The data were collected by the Belle detector at the KEKB e+e- asymmetric energy collider. A clear Λc+ signal is seen in the invariant mass distribution of pη. The fitted number of signal events of the Λc+→pη process is 7734±263; from this, we measure the ratio of branching fractions B(Λc+→pη)/B(Λc+→pK-π+)=[2.258±0.077(stat)±0.122(syst)]×10-2, from which we infer the branching fraction B(Λc+→pη)=[1.42±0.05(stat)±0.11(syst)]×10-3. In addition, no significant signal for Λc+→pπ0 is found, so an upper limit on the branching fraction of B(Λc+→pπ0)

Abstract: Using data samples of 89.5 and 711 fb^{-1} recorded at energies of sqrt[s]=10.52 and 10.58 GeV, respectively, with the Belle detector at the KEKB e^{+}e^{-} collider, we report measurements of branching fractions of semileptonic decays Ξ_{c}^{0}→Ξ^{-}ℓ^{+}ν_{ℓ} (ℓ=e or μ) and the CP-asymmetry parameter of Ξ_{c}^{0}→Ξ^{-}π^{+} decay. The branching fractions are measured to be B(Ξ_{c}^{0}→Ξ^{-}e^{+}ν_{e})=(1.31±0.04±0.07±0.38)% and B(Ξ_{c}^{0}→Ξ^{-}μ^{+}ν_{μ})=(1.27±0.06±0.10±0.37)%, and the decay parameter α_{Ξπ} is measured to be 0.63±0.03±0.01 with much improved precision compared with the current world average. The corresponding ratio B(Ξ_{c}^{0}→Ξ^{-}e^{+}ν_{e})/B(Ξ_{c}^{0}→Ξ^{-}μ^{+}ν_{μ}) is 1.03±0.05±0.07, which is consistent with the expectation of lepton flavor universality. The first measured asymmetry parameter A_{CP}=(α_{Ξ^{-}π^{+}}+α_{Ξ[over ¯]^{+}π^{-}})/(α_{Ξ^{-}π^{+}}-α_{Ξ[over ¯]^{+}π^{-}})=0.024±0.052±0.014 is found to be consistent with zero. The first and the second uncertainties above are statistical and systematic, respectively, while the third ones arise due to the uncertainty of the Ξ_{c}^{0}→Ξ^{-}π^{+} branching fraction.
