Abstract

We investigate the impact of the fourth-generation quarks on production and decays of the charged Higgs boson at CERN Large Hadron Collider (LHC) with 14 TeV center of mass energy. The signal is the process 𝑔𝑔→𝑒4𝑒4, followed by 𝑒4β†’π‘Šβˆ’π‘ and 𝑒4β†’β„Ž+𝑏 decays with subsequent β„Ž+→𝑑𝑏 and corresponding hermitic conjugates. It is shown that if π‘šπ‘’4=400 GeV, then considered process will provide unique opportunity to discover charged Higgs boson with mass range of 200 to 350 GeV at the LHC.
