Mass bounds for triplet scalars of the Left-Right Symmetric Model and their future detection prospects

The standard formulation of the Left-Right symmetric model involves scalars transforming as a triplet under SU(2)L. This multiplet contains particles which are uncharged, singly-charged, and doubly-charged. We derive a bound on the uncharged scalar mass using results from LEP-II and find that a scalar of mass upto 110 GeV may be explored at the NLC. We also discuss search strategies for the singly- and doubly-charged scalars at the Tevatron and the LHC. Possible Standard Model backgrounds for the relevant modes are estimated and compared with the signal. At the LHC, the prospects of detecting the doubly-charged scalar are bright up to a mass of 950 GeV while the 5 sigma discovery limit of the singly-charged mode extends to 440 GeV. At the Tevatron with an integrated luminosity of 2 inv.fb, the singly-charged state can be detected if its mass is less than 140 GeV.
