Status of COMPASS RICH-1 Upgrade with MPGD-based Photon Detectors
M. Alexeev, R Birsa, F. Bradamante +31
A Set of new MPGD-based Photon Detectors is being built for the upgrade of COMPASS RICH-1. The detectors cover a total active area of 1.4 m and are based on a hybrid architectu…
Longitudinal double-spin asymmetry and spin-dependent structure function of the proton at small values of and
M. Aghasyan, R. Akhunzyanov, M. G. Alexeev +225
We present a precise measurement of the proton longitudinal double-spin asymmetry and the proton spin-dependent structure function at photon virtualitie…
Transverse-momentum-dependent Multiplicities of Charged Hadrons in Muon-Deuteron Deep Inelastic Scattering
M. Aghasyan, R. Akhunzyanov, M. G. Alexeev +227
A semi-inclusive measurement of charged hadron multiplicities in deep inelastic muon scattering off an isoscalar target was performed using data collected by the COMPASS Collaborat…
Development and Test of a uTPC Cluster Reconstruction for a Triple GEM Detector in Strong Magnetic Field
R. Farinelli, M. Alexeev, A. Amoroso +43
Performance of triple GEM prototypes has been evaluated by means of a muon beam at the H4 line of the SPS test area at CERN. The data from two planar prototypes have been reconstru…
New analysis of tensor resonances measured at the COMPASS experiment
A. Jackura, C. Fernandez-Ramirez, M. Mikhasenko +232
We present a new amplitude analysis of the -wave in measured by COMPASS. Employing an analytical model based on the principles of the relativistic -mat…
The Cylindrical GEM Inner Tracker of the BESIII experiment: prototype test beam results
L. Lavezzi, M. Alexeev, A. Amoroso +49
A cylindrical GEM detector is under development, to serve as an upgraded inner tracker at the BESIII spectrometer. It will consist of three layers of cylindrically-shaped triple GE…
Search for muoproduction of at COMPASS and indication of a new state
M. Aghasyan, R. Akhunzyanov, M. G. Alexeev +224
We have searched for exclusive production of exotic charmonia in the reaction using COMPASS data collected with incoming muons of…
A custom readout electronics for the BESIII CGEM detector
M. Da Rocha Rolo, M. Alexeev, A. Amoroso +53
For the upgrade of the inner tracker of the BESIII spectrometer, planned for 2018, a lightweight tracker based on an innovative Cylindrical Gas Electron Multiplier (CGEM) detector…
