Direct measurements of the properties of Thick-GEM reflective photocathodes
G. Hamar, M. Baruzzo, C. Chatterjee +12
In the context of the development of novel Thick GEM based detectors of single photons, the high resolution optical system, nicknamed Leopard, providing a detailed surface scanning…
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…
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…
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…
Sivers asymmetry extracted in SIDIS at the hard scale of the Drell-Yan process at COMPASS
C. Adolph, M. Aghasyan, R. Akhunzyanov +223
Proton transverse-spin azimuthal asymmetries are extracted from the COMPASS 2010 semi-inclusive hadron measurements in deep inelastic muon-nucleon scattering in those four regions…
Longitudinal double spin asymmetries in single hadron quasi-real photoproduction at high
COMPASS Collaboration, C. Adolph, R. Akhunzyanov +207
We measured the longitudinal double spin asymmetries for single hadron muo-production off protons and deuterons at photon virtuality < 1(GeV/) for transve…
