Theory Seminar: Monday December 11th, 1pm EST (virtual)


Speaker: Ferenc Pittler (Cyprus Institute)


Title: Pion nucleon scattering in the $\Delta$ channel at the physical point using Lattice QCD


Abstract: The lightest baryonic resonance, the $\Delta$ plays an important role in investigating the physics of compact neutron stars. Obtaining the resonance parameters (mass, couplings, transition matrix elements) from first principles is necessary.  L\"uscher's work provided a theoretical basis for connecting infinite volume resonance parameters to the interaction spectrum in finite volume making possible to study resonances using the euclidean formulation of lattice quantum chromodynamics (LQCD). In this talk present our investigation $\pi-N$ scattering in the $I=3/2,I_3=3/2$ channel using ab-initio lattice simulation at physical pion mass. Assuming Breit-Wigner resonance shape in the scattering amplitude we predict the mass and the coupling of the delta resonance.


See you tomorrow.


Best regards,

Caroline, Joe, and Zheng-Yang
