Laser-assisted CP-odd and CP-even Higgs bosons production in THDM

Abstract In this paper, we have theoretically studied the neutral Higgs pair production in Two Doublet Model (THDM) presence of a circularly polarized laser field. The laser-assisted differential partial cross section is derived centre mass frame at leading order including Z diagram. total computed numerically by integrating over solid angle d Ω . benchmark points are discussed for THDM parameters. first step, analysed ${e}^{+}{e}^{-}\rightarrow h^{0}A^{0}$?> e + − → h 0 A considering H 0 as standard model (SM)-like boson. Then, process H^{\,0}A^{0}$?> H taking h boson SM. For both points, processes depends on produced masses, energy and field addition, maximum occurs high compared to that
