Final COMPASS results on the transverse-spin-dependent azimuthal asymmetries in the pion-induced Drell-Yan process
G. D. Alexeev, M. G. Alexeev, C. Alice +180
The COMPASS Collaboration performed measurements of the Drell-Yan process in 2015 and 2018 using a 190 GeV/c beam impinging on a transversely polarised ammonia target. Comb…

Long term experience with perfluorobutane in COMPASS RICH
F. Bradamante, A. Bressan, A. Cicuttin +16
COMPASS RICH-1 has used high-purity perfluorobutane as radiator gas since 2001. The operation and control of the radiator gas has evolved over years with continuous improvements. W…
