Fermionic decays of scalar leptoquarks and scalar gluons in the minimal four color symmetry model
Fermionic decays of the scalar leptoquarks
and of the scalar gluons predicted by the four color symmetry
model with the Higgs mechanism of the quark-lepton mass splitting are
investigated. Widths and branching ratios of these decays are calculated and
analysed in dependence on coupling constants and on masses of the decaying
particles. It is shown that the decays are
dominant with the widths of order of a few GeV for TeV and with
the total branching ratios close to 1. In the case of the dominant
scalar leptoquark decays are S_1^{(+)}\to cl_j^+, S_1^{(-)}\to \nu_i\tilde b,
S_m\to b\l_j^+, S_m\to c\tilde \nu_j with the total branching ratios

On a possible manifestation of the four color symmetry boson in events at the LHC
The cross section of the pair production in -collisions at
the LHC is calculated with acount of the boson induced by the minimal four
color quark-lepton symmetry(). The invariant mass spectrum
with account of the boson is analysed in dependence on the
mass. The mass region for the boson observable at the LHC is found
in dependence on the significance and on the integrated luminosity.Comment: 11 pages, 2 figures, accepted for publication in Modern Physics
