3 Feb 2008 | | Abstract: | We analyse the possibilities to detect a new $Z^{prime}$ boson in
di-electron events at Tevatron and LHC in the framework of the 331 model with
right-handed neutrinos. Using $par{p}$ collision data collected by the CDF II
detector at Fermilab Tevatron, we find that the 331 $Z^{prime}$ boson is
excluded with masses below 920 GeV. For an integrated luminosity of $100
fb^{-1}$ at LHC, and considering a central value $M_{Z^{prime}}=1500$ GeV, we
obtain the invariant mass distribution in the process $pp o Z^{prime} o
e^{+}e^{-}$, where a huge peak, corresponding to 800 signal events, is found
above the SM background. The number of di-electron events vary from 10000 to 1
in the mass range of $M_{Z^{prime}}=1000-5000$ GeV. | | Source: | arXiv, 0802.0310 | | Services: | Forum | Review | PDF | Favorites | |
