Abstract

The data sample collected in 2011-2013 at the c.m.s. energies between 0.32-2 GeV with the CMD-3 detector operating at the VEPP-2000 e+e− collider is analzed. The collected data corresponds to an integrated luminosity about ∼ 60pb−1. The techniques for determination of the integrated luminosity for each energy setting is described. Some preliminary results of the study of the processes e+e−→ K+ K− + nπ (n = 1,2,3) with two charged kaons in the final state are presented. These processes have several intermediate states, which are important to correctly descript the angular distributions of final particles and the cross sections dependence on the energy.

Abstract

The CMD-3 detector started data taking at the electron-positron collider VEPP-2000 [1] in December 2010. The collected data sample corresponds to an integrated luminosity of 87 pb−1 in the c.m. energy range from 1.06 up to 2 GeV and 91 pb−1 from 0.32 to 1.06 GeV. The integrated luminosity was measured by counting e+e−→ e+e− and e+e−→ γγ events, allowing additional photons in the final state. Preliminary results of the luminosity measurement are presented for various energy ranges and its accuracy is estimated to be 1%.

Abstract

The CMD-3 detector is installed at the VEPP-2000 e+e− collider at BINP (Novosibirsk, Russia). It is a general-purpose detector, equipped with a tracking system, two crystal (CSI and BGO) calorimeters, liquid Xe calorimeter, TOF and muon systems. The main goal of experiments at CMD-3 is a study of exclusive modes of e+e−→ hadrons at energies s≤2$ \sqrt s \le $ GeV. In particular, these results provide an important input for calculation of the hadronic contribution to the muon anomalous magnetic moment. The first round of data taking was performed in 2011–2013, when about 60 1/pb were taken in the center-of-mass (c.m.) energy range from 0.32 to 2.0 GeV. Here we present a survey of results of data analysis. Between 2013 and 2016 the collider and the detector were upgraded. The data taking resumed by the end of 2016. In the first run after the upgrade about 50 1/pb were collected at the energy range between 1.28 and 2.007 GeV. We discuss the upgrade and the first preliminary results from the new data.

Abstract

Since December 2010 the CMD-3 and SND detectors detectors collect data at the VEPP-2000 electron-positron collider. In 2013-2015 the injection facility of the collider has undergone an upgrade of the injection system. The new BINP injection complex has been connected to the VEPP-2000 collider, so the restrictions connected to the lack of positrons and limited beam energy transfer do not apply any more. The collider luminosity in whole energy range is restricted now only by beam-beam effects. VEPP-2000 collider started to collect data with two detectors at 2016 year. The collected data sample since 2010 corresponds more than 100 pb-1 of integrated luminosity per detector in the c.m. energy between 0.32 and 2GeV. We will report here results of analysis of various hadronic cross sections from detectors both published and preliminary. These measurements are important by themselves and also because of the implications for anomaly of the magnetic moment of a muon (g-2) discrepancy.

Abstract

A cross section of the process e+e−→KS0K±π∓π+π− has been measured for the first time using a data sample of 185.4 pb$^{−1}$ collected with the CMD-3 detector at the VEPP-2000 e+e− collider. With the KS0→π+π− decay detection, 373±20 and 514±28 signal events have been selected with six and five reconstructed tracks, respectively, in the center-of-mass energy range 1.6–2.0 GeV. The total systematic uncertainty of the cross section is about 15%. A study of the production dynamics allows us to extract a contribution from the e+e−→f1(1285)π+π− intermediate state and to measure the corresponding cross section. The intermediate states with the f1(1420) and f1(1510) resonances have been observed.

Abstract

The process e+e−→K+K−η has been studied in the center-of-mass energy range from 1.59 to 2.007 GeV using the data sample of 59.5 pb$^{−1}$, collected with the CMD-3 detector at the VEPP-2000 e+e− collider in 2011, 2012 and 2017. The K+K−η final state is found to be dominated by the contribution of the ϕ(1020)η intermediate state. The cross section of the process e+e−→ϕ(1020)η has been measured with a systematic uncertainty of 5.1% on the base of 3009 ± 67 selected events. The obtained cross section has been used to calculate the contribution to the anomalous magnetic moment of the muon: aμϕη(E<1.8GeV)=(0.321±0.015stat±0.016syst)×10−10, aμϕη(E<2.0GeV)=(0.440±0.015stat±0.022syst)×10−10. From the cross section approximation the ϕ(1680) meson parameters have been determined with better statistical precision, than in previous studies.

Abstract

The cross section of the process e+e−→3(π+π−)π0 has been measured for the first time using a data sample of 56.7 pb$^{−1}$ collected with the CMD-3 detector at the VEPP-2000 e+e− collider. 632±32 signal events have been selected in the center-of-mass energy range 1.6–2.0 GeV. A study of dynamics of seven-pion production allows one to extract contributions of the dominated 2(π+π−)ω and 2(π+π−)η intermediate states.

Abstract

Using a data sample of 7.7 pb−1 collected with the CMD-3 detector at the VEPP-2000 e+e− collider we select about 2900 events of the process e+e−→pp¯ and measure its cross section at 12 energy points with about 6% systematic uncertainty. From the angular distribution of produced nucleons we obtain the ratio GE/GM.

Abstract

The photochemical degradation of 2-mercaptobenzothiazole (MBT) and 1,2,3-benzotriazole (BTA) inhibitors was studied in the present work in aqueous and in organic solutions. The extent of photodegradation was assessed by UV-Vis spectroscopy and the main reaction products were identified by tandem electrospray ionization mass spectrometry (ESI-MS/MS). The analysis of degradation products upon UV irradiation revealed the predominant formation of dimeric compounds from MBT and oligomeric structures from BTA, which were further converted into aniline. The increase of the quantum yield of MBT and BTA photodegradation reactions under aerobic conditions both in aqueous and organic solvents was explained by an increase of the spin–orbit conversion of the singlet radical pairs into the triplet radical pairs in the presence of oxygen. These triplet pairs further dissociate into free radicals, or convert to the parent compounds. At the early stage of UV irradiation, free radical coupling leads essentially to dimer formation in the case of MBT and to the formation of oligomers in the case of BTA irradiation.

Abstract

No less than 15–20 sedimentary basins are now known on the Antarctic continental landmass and surrounding continental shelves. Reconstruction of their tectonic and stratigraphic evolution is a specialized task. Owing to the polar position of the continent, the Pacific and Atlantic global geostructures are closely spaced there and the interplay between them is strong enough to result in hybridization of the characteristic tectonic features of the various basins. The present morphostructure of the southern polar region of the Earth is characterized by a prominent circumpolar zoning. Therefore, the sedimentary basins form a gigantic ring along the continental margin, including both the shelf proper and the edge of the continent. Within the ring, the basins are associated with different types of margins successively replacing each other, from the Mesozoic magmatic are in the Pacific segment to the classic passive margin off East Antarctica. The formation of the sedimentary basins in the Antarctic segment of the Pacific mobile belt was a part of a single process of geosynclinal development, whereas on the craton flank the process was superposed on the continental structures by rifting during Gondwana fragmentation. During post-break-up tectonism, continental glaciation played an important part in the formation of the sedimentary basins.

Abstract

The cross section of the process e + e − → π + π − π 0 η has been measured using a data sample of 21.8 pb − 1 collected with the CMD-3 detector at the VEPP-2000 e + e − collider. 2769 ± 95 signal events have been selected in the center-of-mass energy range 1394–2005 MeV. The production dynamics is dominated by the ω ( 782 ) η and ϕ ( 1020 ) η intermediate states in the lower energy range, and by the a 0 ( 980 ) ρ ( 770 ) intermediate state at higher energies.

Abstract

A cross section of the process e + e − → π + π − π + π − has been measured using 6798 ± 93 signal events from a data sample corresponding to an integrated luminosity of 9.8 pb −1 collected with the CMD-3 detector in the center-of-mass energy range 920–1060 MeV. The measured cross section exhibits a pattern of interference of the ϕ ( 1020 ) → π + π − π + π − decay with a non-resonant process e + e − → π + π − π + π − , from which we obtain the branching fraction of the doubly suppressed decays (by G-parity and OZI rule): B ( ϕ → π + π − π + π − ) = ( 6.5 ± 2.7 ± 1.6 ) × 10 − 6 .

Abstract

The process e + e − → K + K − π + π − has been studied in the center-of-mass energy range from 1500 to 2000 MeV using a data sample of 23 pb −1 collected with the CMD-3 detector at the VEPP-2000 e + e − collider. Using about 24 000 selected events, the e + e − → K + K − π + π − cross section has been measured with a systematic uncertainty decreasing from 11.7% at 1500–1600 MeV to 6.1% above 1800 MeV. A preliminary study of K + K − π + π − production dynamics has been performed. [ABSTRACT FROM AUTHOR]

Abstract

A cross section of the process e + e − → K S 0 K ± π ∓ π + π − has been measured for the first time using a data sample of 185.4 pb−1 collected with the CMD-3 detector at the VEPP-2000 e + e − collider. With the K S 0 → π + π − decay detection, 373±20 and 514±28 signal events have been selected with six and five reconstructed tracks, respectively, in the center-of-mass energy range 1.6–2.0 GeV. The total systematic uncertainty of the cross section is about 15%. A study of the production dynamics allows us to extract a contribution from the e + e − → f 1 (1285) π + π − intermediate state and to measure the corresponding cross section. The intermediate states with the f 1 (1420) and f 1 (1510) resonances have been observed. [ABSTRACT FROM AUTHOR]
