Distribution amplitudes of vector and axial-vector mesons in a nonperturbatively improved symmetry-preserving framework
Zhen-Ni Xu, Zhao-Qian Yao, Peng Cheng +1
Using continuum Schwinger-function methods with a nonperturbatively improved, symmetry-preserving kernel, we deliver predictions for the leading-twist light-front distribution ampl…
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…
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…
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 masses…
Bethe-Salpeter kernel and properties of strange-quark mesons
Zhen-Ni Xu, Zhao-Qian Yao, Si-Xue Qin +2
Focusing on the continuum meson bound-state problem, a novel method is used to calculate closed-form Bethe-Salpeter kernels that are symmetry consistent with any reasonable gluon-q…
Heavy + heavy and heavy + light pseudoscalar to vector semileptonic transitions
Hui-Yu Xing, Zhen-Ni Xu, Zhu-Fang Cui +2
Using a symmetry-preserving regularisation of a vectorvector contact interaction (SCI), we complete a systematic treatment of twelve semileptonic transitions with vector me…
Heavy+light pseudoscalar meson semileptonic transitions
Zhen-Ni Xu, Zhu-Fang Cui, Craig D. Roberts +1
A symmetry-preserving regularisation of a vectorvector contact interaction (SCI) is used to deliver a unified treatment of semileptonic transitions involving , , $D_{…
