In this book, we simulated B-L model at Large Hadron Collider by using Monte Carlo simulation software. B-L model is one of many scenarios proposed to add an extension of the Standard Model of particle physics. These scenarios or models try to find a solution for many problems where the Standard Model can not solve it like dark matter, neutrino oscillation. B-L model predicts the existence of three new particles at the LHC. They are new neutral massive gauge boson, three heavy neutrinos (Right-Handed) and new heavy Higgs boson which is different from than Higgs of SM. We simulated these new...
