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…
Distribution Functions of a Radially Excited Pion
Z. -N. Xu, Z. -Q. Yao, D. Binosi +3
A nonperturbatively-improved, symmetry-preserving approximation to the quantum field equations relevant in calculations of meson masses and interactions is used to deliver predicti…
Kaon Distribution Functions from Empirical Information
Zhen-Ni Xu, Daniele Binosi, Chen Chen +3
Using available information from Drell-Yan data on pion and kaon structure functions, an approach is described which enables the development of pointwise profiles for all pion and…
Heavy-light Pseudoscalar Mesons: Light-Front Wave Functions and Generalized Parton Distributions
B. Almeida-Zamora, J. J. Cobos-MartÃnez, A. Bashir +3
The internal structure of the lowest-lying pseudo-scalar mesons with heavy-light quark content is thoroughly studied using an algebraic model that has been successfully applied to…
Nucleon Gravitational Form Factors
Z. -Q. Yao, Y. -Z. Xu, D. Binosi +6
A symmetry-preserving analysis of strong interaction quantum field equations is used to complete a unified treatment of pion, kaon, nucleon electromagnetic and gravitational form f…
