// ClassName:   G4HadronPhysicsQGSP_BIC_HP
//
// Author: 2006 G.Folger
//
// Based on G4HadronPhysicsQGSP_BIC
//
// Modified:
// 25.04.2007 G.Folger: Add code for quasielastic
// 31.10.2012 A.Ribon: Use G4MiscBuilder
// 19.03.2013 A.Ribon: Replace LEP with FTFP and BERT
// 05.05.2020 A.Ribon: Use QGSP for antibaryons at high energies
// 07.05.2020 A.Ribon: Use QGSP for hyperons (and anti-hyperons) at high energies
// 20.05.2020 A.Ribon: Refactoring of the class (keeping same functionalities)
