Transverse spin effects in COMPASS
نویسنده
چکیده
In the years 2002-2004 COMPASS has collected data with the LiD target polarization oriented transversely with respect to the muon beam direction for about 20% of the running time, to measure transverse spin effects in semi-inclusive deep inelastic scattering, one of the main objectives of the COMPASS spin program. In 2007, COMPASS has used for the first time a proton NH3 target with the data taking time equally shared between longitudinal and transverse polarization of the target. After reviewing the results obtained with the deuteron, the new results for the Collins and Sivers asymmetries of the proton will be presented.

Transverse Spin Effects at COMPASS
The investigation of transverse spin and transverse momentum effects in deep inelastic scattering is one of the key physics programs of the COMPASS collaboration. In the years 2002-2004 COMPASS took data scattering 160 GeV muons on a transversely polarized LiD target. In 2007, a transversely polarized NH3 target was used. Three different channels to access the transversity distribution function...
متن کاملTransverse spin azimuthal asymmetries in SIDIS at COMPASS: Multidimensional analysis
COMPASS is a high-energy physics experiment operating at the SPS at CERN. Wide physics program of the experiment comprises study of hadron structure and spectroscopy with high energy muon and hadrons beams. As for the muon-program, one of the important objectives of the COMPASS experiment is the exploration of the transverse spin structure of the nucleon via spin (in)dependent azimuthal asymmet...
متن کاملMeasurement of Transverse Spin Effects at COMPASS
By measuring transverse single spin asymmetries one has access to the transversity distribution function ∆T q(x) and the transverse momentum dependent Sivers function q T 0 (x,~kT ). New measurements from identified hadrons and hadron pairs, produced in deep inelastic scattering of a transversely polarized LiD target are presented. The data were taken in 2003 and 2004 by the COMPASS collaborati...

Successful realization of polarized Drell-Yan physics program is one of the main goals of the second stage of the COMPASS experiment. Drell-Yan measurements with high energy (190 GeV/c) pion beam and transversely polarized NH3 target have been initiated by a pilot-run in the October 2014 and will be followed by 140 days of data taking in 2015. In the past twelve years COMPASS experiment perform...
متن کاملTransverse Spin Effects at COMPASS
The measurement of transverse spin effects in semi-inclusive deepinelastic scattering (SIDIS) is an important part of the COMPASS physics program. In the years 2002-2004 data was taken by scattering a 160GeV/c muon beam off a transversely polarized deuteron target. In 2007, additional data was collected on a transversely polarized proton target. New preliminary results for the Collins and Siver...
