Roy-Steiner equations for
Martin Hoferichter, Daniel R. Phillips, Carlos Schat
Starting from hyperbolic dispersion relations, we present a system of Roy--Steiner equations for pion Compton scattering that respects analyticity and unitarity requirements, gauge…
Roy-Steiner equations for gamma gamma -> pi pi
Martin Hoferichter, Daniel R. Phillips, Carlos Schat
Starting from hyperbolic dispersion relations, we derive a system of Roy--Steiner equations for pion Compton scattering that respects analyticity, unitarity, gauge invariance, and…
Matching the quark model to the 1/Nc expansion
Dan Pirjol, Carlos Schat
We compute the coefficients of the effective mass operator of the 1/Nc expansion for negative parity L=1 excited baryons using the Isgur-Karl model in order to compare the general…
Testing for three-body quark forces in L=1 excited baryons
Dan Pirjol, Carlos Schat
We discuss the matching of the quark model to the effective mass operator of the 1/Nc expansion using the permutation group S_N. As an illustration of the general procedure we perf…
1/Nc expansion and the spin-flavor structure of the quark interaction in the constituent quark model
Dan Pirjol, Carlos Schat
We study the hierarchy of the coefficients in the 1/Nc expansion for the negative parity L=1 excited baryons from the perspective of the constituent quark model. This is related to…
Vertex Displacements for Acausal Particles: Testing the Lee-Wick Standard Model at the LHC
Ezequiel Alvarez, Leandro Da Rold, Carlos Schat +1
We propose to search for wrong displaced vertices, where decay products of the secondary vertex move towards the primary vertex instead of away from it, as a signature for microsco…
