Valence Quark and Gluon Distributions of Kaon from J/Psi Production
Jen-Chieh Peng, Wen-Chen Chang, Stephane Platchkov +1
The only experimental information on the parton distribution of kaons was obtained from the scarce kaon-induced Drell-Yan cross section data. From these data, evidence for a valenc…
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…
Dependencies of Lepton Angular Distribution Coefficients on the Transverse Momentum and Rapidity of Bosons Produced in Collisions at LHC
Wen-Chen Chang, Randall Evan McClellan, Jen-Chieh Peng +1
High precision data of lepton angular distributions for production in collisions at the LHC, covering broad ranges of dilepton transverse momenta () and rapidity…
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…
First measurement of the Sivers asymmetry for gluons from SIDIS data
C. Adolph, M. Aghasyan, R. Akhunzyanov +223
The Sivers function describes the correlation between the transverse spin of a nucleon and the transverse motion of its partons. It was extracted from measurements of the azimuthal…
