FOTON-FOTON ÇARPIŞMALARI İLE HİGGS BOZON ÇİFTLERİNİN 2HDM'YE GÖRE MEYDANA GELME OLASIĞININ HESAPLANMASI VE MONTE CARLO SİMÜLASYONU
Project no. 454 · Status: Kapanmış · 2017
Summary
In this project, triple Higgs boson production channels in a gamma-gamma collider are investigated in the context of the two-Higgs-doublet model (2HDM) and Supersymmetry theory. Both of these models contain three neutral Higgs bosons (h^0/H^0/A^0) and two charged Higgs bosons (H^±). Between all the possible combinations of the triple Higgs bosons in the final state, only the following two scattering processes are probable at tree-level; They are gamma-gamma-›H^+ H^- h^0 and gamma-gamma -› H^+ H^- H^0. These two scattering processes are very important to determine the triple Higgs self-couplings g_(H^+ H^- h^0 ) and g_(H^+ H^- H^0 ) in the 2HDM. The calculation is carried out for two scenarios which are inspired by the latest experimental and theoretical results. The cross-section of these scattering processes is calculated, and comparison is made. The total convoluted cross-section with photon luminosity in an e^+ e^--collider is presented as a function of the center of mass-energy.
