Bound states of singlet quarks at LHC

We discuss the discovery potential of the bound states of singlet quarks at LHC. We find that it is possible to discover bound states of singlet quarks at LHC with singlet quark masses up to 300 Gev for eQ = 2 3 and up to 200 Gev for eQ = − 1 3 .

A brief review of checking the factorization hypothesis for matrix element of B 0 − ¯ B 0 mixing within operator product expansion and QCD sum rules is given. Both perturbative and power corrections are considered.

A complete characterization of all the possible effective interactions up to dimension 5 of the top and bottom quarks with the electroweak gauge bosons have been made within the context of the chiral Lagrangian. We show that the anomalous dimension 5 operators (19 in total) can contribute to the leading energy power (E 3 for fermion pairs with same sign helicities and E 2 for opposite sign heli...

We present some recent advances in the computational study of baryon number violation in high energy electroweak collisions. We examine classically allowed processes above the sphaleron barrier and, using a stochastic search procedure, we explore the topology changing region in the energy and particle number plane. Finding topology changing classical solutions with small incident particle numbe...
