Constraining gluon density of pions at large by pion-induced production
Wen-Chen Chang, Jen-Chieh Peng, Stephane Platchkov +1
The gluon distributions of the pion obtained from various global fits exhibit large variations among them. Within the framework of the color evaporation model, we show that the exi…
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…
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…
Accessing proton generalized parton distributions and pion distribution amplitudes with the exclusive pion-induced Drell-Yan process at J-PARC
Takahiro Sawada, Wen-Chen Chang, Shunzo Kumano +3
Generalized parton distributions (GPDs) encoding multidimensional information of hadron partonic structure appear as the building blocks in a factorized description of hard exclusi…
Nucleon sea and the five-quark components
Jen-Chieh Peng, Wen-Chen Chang
We generalize the approach of Brodsky {\it et al.} for the intrinsic charm quark distribution in the nucleons to the light-quark sector involving intrinsic and…
Flavor Asymmetry of the Nucleon Sea and the Five-Quark Components of the Nucleons
Wen-Chen Chang, Jen-Chieh Peng
The existence of the five-quark Fock states for the intrinsic charm quark in the nucleons was suggested some time ago, but conclusive evidence is still lacking. We generalize the p…
