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…
Diquark size effects in the quark-diquark approximation for baryons
Clara Tourbez, Cyrille Chevalier, Claude Semay
Baryons can be described within several theoretical frameworks. Among them, the constituent approach is widely used. In this context, we aim to evaluate the accuracy of a particula…
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…
Three-body Forces in Oscillator Bases Expansion
Cyrille Chevalier, Selma Youcef Khodja
The oscillator bases expansion stands as an efficient approximation method for the time-independent Schrödinger equation. The method, originally formulated with one non-linear vari…
Tests of the envelope theory for three-body forces
Lorenzo Cimino, Clara Tourbez, Cyrille Chevalier +2
Many-body forces, and specially three-body forces, are sometimes a relevant ingredient in various fields, such as atomic, nuclear or hadronic physics. As their precise structure is…
