Phenomenology of Hidden Abelian Higgs Model at Hadron Colliders using Neural Networks and Monte Carlo Techniques (Gauge Sector $Z_{HAHM}$ & Scalar Sector H)

The Hidden Abelian Higgs Model (HAHM) is an extension of the Standard Model based on the gauge group $G =SU(3){C} \times SU(2){L} \times U(1){Y} \times U(1){X}$i\mathrm{.}e\mathrm{.}anextra$U(1){X}$ gauge group in addition to the SM gauge groups.In HAHM, an Abelian Hidden sector is coupled to the SM, and the resulting new Higgs boson H and new neutral gauge boson $Z_{HAHM}$ fields are allowed to mix with the corresponding SM fields. In this work, we search for the new neutral gauge boson $Z_{HAHM}$ and new Higgs boson in the context of the Hidden Abelian Higgs Model (HAHM) through the decay process $pp(\bar{p})\rightarrow H\rightarrow Z{HAHM}Z_{HAHM}\rightarrow $\mathit{\text{l}}$^{\pm}$\mathit{\text{l}}$^{\mp}$\mathit{\text{l}}$^{\pm}$\mathit{\text{l}}$^{\mp},($\mathit{\text{l}}$=e,\mu)$with4chargedleptonsinthefinalstateinthemassrange$200\leq Z_{HAHM} \leq 700$ GeV and the production and decay of new Higgs boson with 2 charged leptons in the final state of the process $pp(\bar{p})\rightarrow H\rightarrow$\mathit{\text{l}}$^{\pm}$\mathit{\text{l}}$^{\mp}jj ,($\mathit{\text{l}}$=e,\mu)$ with jets or final state of the proces $pp(\bar{p})\rightarrow H\rightarrow $\mathit{\text{l}}$^{\pm}$\mathit{\text{l}}$^{mp}\nu\bar{\nu},(l=e,\mu)$ with missing energy.We used Monte Carlo data produced from proton-proton collisions at the LHC CERN (CMS and ATLAS detectors) for different center of mass energies up to $\sqrt{s}=14TeV$
