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…

Upper bounds for critical coupling constants for binding some quantum many-body systems
Clara Tourbez, Claude Semay, Cyrille Chevalier
When particles interact via two-body short-range central potential wells, binding can occur for some critical values of the coupling constants. Using the envelope theory, upper bou…
