Abstract: We present a measurement of the momentum spectra of π $^{±}$, K$^{±}$, p$^{±}$, Λ, $\overline{Λ}$, and K$^{0}$$_{S}$ produced in interactions of negatively charged pions with carbon nuclei at beam momenta of 158 and 350 GeV/c. The total production cross sections are measured as well. The data were collected with the large-acceptance spectrometer of the fixed target experiment NA61/SHINE at the CERN SPS. The obtained double-differential p−pT spectra provide a unique reference dataset with unprecedented precision and large phase-space coverage to tune models used for the simulation of particle production in extensive air showers in which pions are the most numerous projectiles.

Abstract: This paper presents measurements of production cross sections and inelastic cross sections for the following reactions: 60 GeV/c protons with C, Be, Al targets and 120 GeV/c protons with C and Be targets. The analysis is performed using the NA61/SHINE spectrometer at the CERN Super Proton Synchrotron. First measurements are obtained using protons at 120 GeV/c, while the results for protons at 60 GeV/c are compared with previously published measurements. These interaction cross section measurements are critical inputs for neutrino flux prediction in current and future accelerator-based long-baseline neutrino experiments. publishedVersion

Abstract: Precise knowledge of hadron production rates in the generation of neutrino beams is necessary for accelerator-based neutrino experiments to achieve their physics goals. NA61/SHINE, a large-acceptance hadron spectrometer, has recorded hadron+nucleus interactions relevant to ongoing and future long-baseline neutrino experiments at Fermi National Accelerator Laboratory. This paper presents three analyses of interactions of 60 GeV/c π+ with thin, fixed carbon and beryllium targets. Integrated production and inelastic cross sections were measured for both of these reactions. In an analysis of strange, neutral hadron production, differential production multiplicities of K0S, Λ and ¯Λ were measured. Lastly, in an analysis of charged hadron production, differential production multiplicities of π+, π−, K+, K− and protons were measured. These measurements will enable long-baseline neutrino experiments to better constrain predictions of their neutrino flux in order to achieve better precision on their neutrino cross section and oscillation measurements. publishedVersion

Abstract: Structure of the decay B̄s0→J/ψπ+π- is studied using data corresponding to 3fb-1 of integrated luminosity from pp collisions produced by the LHC and collected by the LHCb detector. Five interfering π+π- states are required to describe the decay: f0(980),f0(1500),f0(1790),f2(1270), and f2′(1525). An alternative model including these states and a nonresonant J/ψπ+π- component also provides a good description of the data. Based on the different transversity components measured for the spin-2 intermediate states, the final state is found to be compatible with being entirely CP odd. The CP-even part is found to be

Abstract: We present a measurement of the ratio of the Bs meson lifetime, in the flavor-specific decay to $D_s^+\pi^-$, to that of the B0 meson. The pp collision data used correspond to an integrated luminosity of 1/fb, collected with the LHCb detector, at a center-of-mass energy of 7 TeV. Combining our measured value of 1.010 +/- 0.010 +/- 0.008 for this ratio with the known lifetime, we determine the flavor-specific Bs lifetime to be tau(Bs) = 1.535 +/- 0.015 +/- 0.014 ps, where the uncertainties are statistical and systematic, respectively. This is the most precise measurement to date, and is consistent with previous measurements and theoretical predictions.

Abstract: Structure of the decay B¯0s→J/ψπ+π− is studied using data corresponding to 3 fb−1 of integrated luminosity from pp collisions produced by the LHC and collected by the LHCb detector. Five interfering π+π− states are required to describe the decay: f0(980),f0(1500),f0(1790),f2(1270), and f′2(1525). An alternative model including these states and a nonresonant J/ψπ+π− component also provides a good description of the data. Based on the different transversity components measured for the spin-2 intermediate states, the final state is found to be compatible with being entirely CP odd. The CP-even part is found to be

Abstract: First observations of the decays Λ0b→Λ+cD−(s) are reported using data corresponding to an integrated luminosity of 3 fb−1 collected at 7 and 8 TeV center-of-mass energies in proton-proton collisions with the LHCb detector. In addition, the most precise measurement of the branching fraction B(B0s→D+D−s) is made and a search is performed for the decays B0(s)→Λ+cΛ−c. The results obtained are\ud B(Λ0b→Λ+cD−)/B(Λ0b→Λ+cD−s)=0.042±0.003(stat)±0.003(syst),[B(Λ0b→Λ+cD−s)B(B¯0→D+D−s)]/[B(Λ0b→Λ+cπ−)B(B¯0→D+π−)]=0.96±0.02(stat)±0.06(syst),B(B0s→D+D−s)/B(B¯0→D+D−s)=0.038±0.004(stat)±0.003(syst),B(B¯0→Λ+cΛ−c)/B(B¯0→D+D−s)

Abstract: A search for heavy Majorana neutrinos produced in the B−→π+μ−μ− decay mode is performed using 3 fb−1 of integrated luminosity collected with the LHCb detector in pp collisions at center-of-mass energies of 7 and 8 TeV at the LHC. Neutrinos with masses in the range 250 to 5000 MeV and lifetimes from zero to 1000 ps are probed. In the absence of a signal, upper limits are set on the branching fraction B(B−→π+μ−μ−) as functions of neutrino mass and lifetime. These limits are on the order of 10−9 for short neutrino lifetimes of 1 ps or less. Limits are also set on the coupling between the muon and a possible fourth-generation neutrino.

Abstract: The first measurement of the effective lifetime of the B¯0s meson in the decay B¯0s→D−sD+s is reported using a proton-proton collision data set, corresponding to an integrated luminosity of 3 fb−1, collected by the LHCb experiment. The measured value of the B¯0s→D−sD+s effective lifetime is 1.379±0.026±0.017 ps, where the uncertainties are statistical and systematic, respectively. This lifetime translates into a measurement of the decay width of the light B¯0s mass eigenstate of ΓL=0.725±0.014±0.009 ps−1. The B¯0s lifetime is also measured using the flavor-specific B¯0s→D−D+s decay to be 1.52±0.15±0.01 ps.

Abstract: Decays of beauty baryons to the D0ph− and Λþ\ud c h− final states (where h indicates a pion or a kaon) are\ud studied using a data sample of pp collisions, corresponding to an integrated luminosity of 1.0 fb−1,\ud collected by the LHCb detector. The Cabibbo-suppressed decays Λ0\ud b → D0pK− and Λ0\ud b → Λþ\ud c K− are\ud observed, and their branching fractions are measured with respect to the decays Λ0\ud b → D0pπ− and\ud Λ0\ud b → Λþ\ud c π−. In addition, the first observation is reported of the decay of the neutral beauty-strange baryon\ud Ξ0\ud b to the D0pK− final state, and a measurement of the Ξ0\ud b mass is performed. Evidence of the Ξ0\ud b → Λþ\ud c K−\ud decay is also reported.

Abstract: The charmless decays B±→K+K−π± and B±→π+π−π± are reconstructed in a data set of pp collisions with an integrated luminosity of 1.0 fb−1 and center-of-mass energy of 7 TeV, collected by LHCb in 2011. The inclusive charge asymmetries of these modes are measured to be ACP(B±→K+K−π±)=−0.141±0.040 (stat)±0.018 (syst)±0.007(J/ψ K±) and ACP(B±→π+π−π±)=0.117±0.021 (stat)±0.009 (syst)±0.007(J/ψ K±), where the third uncertainty is due to the CP asymmetry of the B±→J/ψK± reference mode. In addition to the inclusive CP asymmetries, larger asymmetries are observed in localized regions of phase space.

Abstract: 6 pages, 6 figures, A search for heavy Majorana neutrinos produced in the $B^- \to \pi^+\mu^-\mu^-$ decay mode is performed using 3 fb$^{-1}$ of integrated luminosity collected with the LHCb detector in $pp$ collisions at center-of-mass energies of 7 TeV and 8 TeV at the LHC. Neutrinos with masses in the range 250-5000 MeV and lifetimes from zero to 1000 ps are probed. In the absence of a signal, upper limits are set on the branching fraction ${\cal{B}}(B^- \to \pi^+\mu^-\mu^-)$ as functions of neutrino mass and lifetime. These limits are on the order of $10^{-9}$ for short neutrino lifetimes of 1 ps or less. Limits are also set on the coupling between the muon and a possible fourth-generation neutrino.

Abstract: This Letter presents a study of the flavor-changing neutral current radiative B±→K±π∓π±γ decays performed using data collected in proton-proton collisions with the LHCb detector at 7 and 8 TeV center-of-mass energies. In this sample, corresponding to an integrated luminosity of 3 fb-1, nearly 14 000 signal events are reconstructed and selected, containing all possible intermediate resonances with a K±π∓π± final state in the [1.1,1.9] GeV/c2 mass range. The distribution of the angle of the photon direction with respect to the plane defined by the final-state hadrons in their rest frame is studied in intervals of K±π∓π± mass and the asymmetry between the number of signal events found on each side of the plane is obtained. The first direct observation of the photon polarization in the b→sγ transition is reported with a significance of 5.2σ.

Abstract: A search for heavy Majorana neutrinos produced in the B- → π+ μ- μ- decay mode is performed using 3 fb(-1) of integrated luminosity collected with the LHCb detector in pp collisions at center-of-mass energies of 7 and 8 TeV at the LHC. Neutrinos with masses in the range 250 to 5000 MeV and lifetimes from zero to 1000 ps are probed. In the absence of a signal, upper limits are set on the branching fraction B(B- → π+ μ- μ-) as functions of neutrino mass and lifetime. These limits are on the order of 10(-9) for short neutrino lifetimes of 1 ps or less. Limits are also set on the coupling between the muon and a possible fourth-generation neutrino.

Abstract: The first measurement of the effective lifetime of the B(s)(0) meson in the decay B(s)(0) → Ds-Ds+ is reported using a proton-proton collision data set, corresponding to an integrated luminosity of 3 fb(-1), collected by the LHCb experiment. The measured value of the B(s)(0) → Ds-Ds+ effective lifetime is 1.379 ± 0.026 ± 0.017 ps, where the uncertainties are statistical and systematic, respectively. This lifetime translates into a measurement of the decay width of the light B(s)(0) mass eigenstate of ΓL = 0.725 ± 0.014 ± 0.009 ps(-1). The B(s)(0) lifetime is also measured using the flavor-specific B(s)(0)→ D-Ds+ decay to be 1.52 ± 0.15 ± 0.01 ps.
