Quest for an Understanding of Pion and Kaon Structure
Zhen-Ni Xu, Daniele Binosi, Craig D. Roberts +1
The emergence of massless (Nambu-Goldstone) bosons in association with a dynamically global broken symmetry is a long known and widespread phenomenon in physics. However, practical…
Pseudoscalar charmonium and bottomonium: light-front wave functions, distribution amplitudes and distribution functions
Zhen-Ni Xu, Zhao-Qian Yao, Cédric Mezrag +2
Light-front wave functions play a central role in the program of understanding the structure of hadrons as QCD bound states. Using continuum Schwinger methods, based on Dyson-Schwi…
Symmetry-preserving calculation of pion light-front wave functions
Zhao-Qian Yao, Zhen-Ni Xu, Yu-Yang Xiao +2
Poincaré-covariant Bethe-Salpeter wave functions are used to calculate light-front wave functions (LFWFs) of the pion, , and an analogue state, . The current mas…
Mapping spatial distributions within pseudoscalar mesons
K. Raya, A. Bashir, J. RodrÃguez-Quintero
Several aspects of the internal structure of pseudoscalar mesons, accessible through generalized parton distributions in their zero-skewness limit, are examined. These include elec…
