Non-perturbative approach to the problem of anomalous FB asymmetry in top pair production at TEVATRON | | Boris A. Arbuzov

4 Feb 2013 | | Abstract: | We apply Bogoliubov compensation principle to the problem of forward-backward
asymmetry in $t ar t$ production at TEVATRON. The non-trivial solution of
compensation equation for anomalous four-fermion interaction effective
interaction of doublets of heavy and light quarks leads to possibility of
existence of $ar t u,, ar b d$ vector bound states (resonance). The
coupling of the bound state to $ar t,,u$ pair is calculated. With this
result we obtain satisfactory description of totality of data on the effect of
FB asymmetry including slope of effect dependence on invariant $t ar t$ mass.
Predictions for the resonance mass and production cross-section at LHC are
presented. | | Source: | arXiv, 1302.0663 | | Services: | Forum | Review | PDF | Favorites | |
