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…
Pion structure from its light-front wave function
Khépani Raya, Zhen-Ni Xu, Zhao-Qian Yao +1
Understanding the structural properties of the pion is essential for elucidating the mechanisms of mass generation within the Standard Model and their role in the emergence and pro…
Contact interaction treatment of the nucleon Faddeev equation
Xin-Yu Bai, Ya Lu, Zhao-Qian Yao +2
Working with a symmetry-preserving treatment of a vector*vector contact interaction (SCI), a largely algebraic three-body Faddeev equation treatment of the nucleon bound state prob…
Constraining the Energy Momentum Tensor through DVCS Dispersion Relation beyond Leading Power
VÃctor MartÃnez-Fernández, Daniele Binosi, Cédric Mezrag +1
In this letter, we analyse and interpret the kinematic power corrections to deeply virtual Compton scattering dispersion relation. We show that the kinematic corrections at twist-4…
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…
Pion, Kaon and nucleon gravitational form factors
Zhao-Qian Yao, Yin-Zhen Xu, Daniele Binosi +5
A unified set of predictions for pion, kaon and nucleon gravitational form factors is obtained using a symmetry-preserving truncation of each relevant quantum field equation. A cru…
