Contact interaction treatment of π and ρ elastic and transition tensor form factors
Ke-Yu Guo, Ke-Xin Zeng, Xin-Yu Bai +2
Predictions for tensor charges and form factors, elastic and transition, involving - and -mesons and their scalar and axialvector diquark partners, are delivered using a symm…
Origin of the nucleon gravitational form factor : Exposition in light-front holographic QCD
Xianghui Cao, Bheemsehan Gurjar, Chandan Mondal +2
Recent lattice QCD simulations and phenomenological models indicate that the nucleon's gravitational form factor remains remarkably small at finite momentum transfer .…
Screening masses of positive- and negative-parity hadron ground-states, including those with strangeness
Chen Chen, Fei Gao, Si-xue Qin
Using a symmetry-preserving treatment of a vector vector contact interaction (SCI) at nonzero temperature, we compute the screening masses of flavour-SU(3) ground-state $J…
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…
Nucleon to axial and pseudoscalar transition form factors
Chen Chen, Christian S. Fischer, Craig D. Roberts
A symmetry-preserving continuum approach to the calculation of baryon properties in relativistic quantum field theory is used to predict all form factors associated with nucleon-to…
