Alternative Left-Right Symmetric Model


Mustafa Ashry




Model Description

As any other left-right symmetric model, ALRM is a QFT gauged by the gauge symmetry group SU(3)_C×SU(2)_L×SU(2)_R×U(1)_B-L. The latter B and L being the baryon and lepton numbers. An extra discrete symmetry S is imposed to distinguish between Higgs fields and their dual fields and hence their interactions.




The model contains ten physical Higgs bosons: four neutral CP-even higgs bosons, one (the lightest) of which is considered to be the SM-like one with mass fixed to have the value mh=125 GeV. Four charged Higgs bosons and two CP-odd pseudoscalar Higgs bosons. The mass spectrum is calculated and the rotation matrices are implemented analytically.


The effective loop-induced h->gg and h->gammagamma, Zgamma, ZZ decays were added. For the complete pp->gammagamma analysis, Madgraph is used for generating events, Pythia is used for parton showering (PS), matrix element (ME) and PS merging, hadronization and jet matching and Madanalysis is used for event file analysis, recasting the LHC results and to produce this histogram figure (to be improved):
