Pion Polarizabilities at CERN COMPASS

open access: yes, 2002
The electric alpha and magnetic beta pion Compton polarizabilities characterize the pion's deformation in the electromagnetic field of the gamma during gamma-pi Compton scattering.

Internal structure of the Tcc(3875)+ from its light-quark mass dependence

open access: yesPhysics Letters B
We employ a chiral effective field theory-based approach to connect DD⁎ scattering observables at the physical and variable pion masses accessible in lattice QCD simulations.

An improved hadronic model for pion electroproduction

open access: yesPhysics Letters B, 2020
Current measurements of the high energy behavior of the pion form factor are obtained from pion electroproduction data. These values are model dependent, utilizing the Vanderhaeghen, Guidal and Laget Regge (VGL) Model for their extraction.

Chiral extrapolation of the sigma resonance

open access: yesPhysics Letters B, 2018
We analyze results on isoscalar ππ scattering from a Nf=2+1 lattice QCD calculation by the HadronSpectrum collaboration by re-summing the two-flavor chiral scattering amplitude of the next-to-leading order in the so-called inverse amplitude method.
