A two-phase argon avalanche detector operated in a single electron counting mode
A. Bondar, A. Buzulutskov, A. Grebenuk +6
The performance of a two-phase Ar avalanche detector in a single electron counting mode was studied, with regard to potential application in coherent neutrino-nucleus scattering an…
Search for Invisible Decay of the
The Belle Collaboration, O. Tajima, H. Hayashii +4
We report results of a search for the invisible decay of the Upsilon(1S) via the Upsilon(3S)->pi+pi-Upsilon(1S) transition using a data sample of 2.9 fb^{-1} at the Upsilon(3S) res…
Triple-GEM performance in He-based mixtures
A. Bondar, A. Buzulutskov, L. Shekhtman +1
The performance of triple-GEM detectors in He+N2 gas mixtures is studied in the range of 1-10 atm. The results obtained are relevant in the field of minimization of ionic space-cha…
Measurement of the e+e- -> pi+pi- cross section with the CMD-2 detector in the 370-520 MeV c.m. energy range
R. R. Akhmetshin, V. M. Aulchenko, V. Sh. Banzarov +50
The cross section of the process e+e- -> pi+pi- has been measured at the CMD-2 detector in the 370-520 MeV center-of-mass (c.m.) energy range. A systematic uncertainty of the measu…
Electric and Photoelectric Gates for ion backflow suppression in multi-GEM structures
A. Buzulutskov, A. Bondar
A new approach to suppress ion backflow in multi-GEM structures is suggested. In this approach, the potential difference applied across the gap between two adjacent GEMs is reverse…
Evidence for B-> eta' pi and improved measurements for B-> eta' K
The Belle Collaboration, J. Schuemann
We report evidence for exclusive two-body charmless hadronic B meson decays B-> eta' pi, and improved measurements of B-> eta' K. The results are obtained from a data sample of 386…
