Single hadron transverse spin asymmetries from COMPASS
نویسنده
چکیده
Transverse spin physics is an important part of the scientific programme of the COMPASS experiment at CERN. The analysis of the data taken with the target polarized orthogonally to the 160 GeV/c muon beam momentum has allowed to measure for the first time the Collins and Sivers asymmetries of the deuteron. Both for the positive and the negative hadrons produced in semi-inclusive DIS the measured asymmetries are small and, within errors, compatible with zero. New results for π ans K are presented here. PACS: 13.60.-r, 13.88.+e, 14.20.Dh, 14.65.-q

Transverse 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...
متن کاملSpin Physics with COMPASS
COMPASS is a fixed target experiment at CERN studying the spin structure of the nucleon via deep inelastic muon-nucleon scattering. Hadron spectroscopy and structure are investigated using hadronic beams. The main goal of the muon program is the determination of the gluon helicity contribution, ∆G/G, to the nucleon spin. Experimentally this quantity is accessible via the measurement of double s...
متن کاملTransverse target spin asymmetries on a proton target at COMPASS
Transversity and transverse momentum-dependent parton distribution functions (TMDs) are been measured in semi-inclusive deep inelastic scattering (SIDIS) by using a transversely polarized target at the COMPASS experiment. COMPASS is a fixed target experiment at the CERN M2 beamline, which provides a 160 GeV/c polarized μ+ beam. In the years 2002-2004 COMPASS has collected data with a transverse...
متن کاملTransverse 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...
