Search for Standard Higgs Boson at Supercolliders
We review the standard Higgs boson physics and the search for higgs boson at
LEP and LHC supercollidersComment: latex, 70 pages, 15 ps.figure
Search for new physics at LHC
We review the search for new physics to be performed at the Large Hadron
Collider(LHC). Namely, we review the expectations for the Higgs boson,
supersymmetry and exotica detection at LHC. We also describe the main
parameters of the CMS and ATLAS detectors.Comment: 93 pages, 31 figures, added reference
Prospects of detecting massive isosinglet neutrino at LHC in the CMS detector
A possibility to search for a heavy isosinglet (sterile) neutrino using its
decay mode in the - channel production in the CMS experiment is studied. The only
assumption about the heavy neutrino is its nonzero mixing with or
. The corresponding CMS discovery potential expressed in terms of
the heavy neutrino mass and the mixing parameter between the heavy and light
neutrino is determined. It is shown that the heavy neutrino with a mass up to
800 could be detected in CMS. We also investigate the production of the
heavy neutrino mixed with and/or in the model through the reaction with the same heavy neutrino decay channel as
above. We find that for it is possible to discover the heavy
neutrino with a mass up to .Comment: 14 pages, 13 figure
Relativistic model of hidden bottom tetraquarks
The relativistic model of the ground state and excited heavy tetraquarks with
hidden bottom is formulated within the diquark-antidiquark picture. The diquark
structure is taken into account by calculating the diquark-gluon vertex in
terms of the diquark wave functions. Predictions for the masses of bottom
counterparts to the charm tetraquark candidates are given.Comment: 6 page
