Light hybrid baryons in the constituent model of QCD
Joachim Viseur, Claude Semay, Cyrille Chevalier
Hybrid baryons, in which gluonic degrees of freedom play an explicit dynamical role, provide a key testing ground for nonperturbative quantum chromodynamics. In this work, we inves…

Handling the Cornell potential within the Lagrange-mesh method in momentum space
Cyrille Chevalier, Joachim Viseur
This work presents an alternative methodology for computing potentials matrix elements within the Lagrange-mesh method in momentum space. The proposed approach extends the range of…

Accuracy Tests of the Envelope Theory
Lorenzo Cimino, Cyrille Chevalier, Ethan Carlier +1
The envelope theory is an easy-to-use approximation method to obtain eigensolutions for some quantum many-body systems, in particular in the domain of hadronic physics. Even if the…
