Search for single vector-like quarks in $p\bar{p}$ collisions at $\sqrt{s} = 1.96$ TeV

Victor Mukhamedovich Abazov, Jinr Dubna, B. Abbott, /Oklahoma U. et autres

We present a search for hypothetical vector-like quarks in p{bar p} collisions at {radical}s = 1.96 TeV. The data were collected by the D0 detector at the Fermilab Tevatron Collider and correspond to an integrated luminosity of 5.4 fb{sup -1}. We select …

Measurement of the $WZ\rightarrow \ell\nu\ell\ell$ cross section and limits on anomalous triple gauge couplings in $p\bar{p}$ collisions at $\sqrt{s}$ = 1.96 TeV

Victor Mukhamedovich Abazov, Jinr Dubna, B. Abbott, /Oklahoma U. et autres

The standard model (SM) of particle physics has been extensively tested in the past three decades and is found to be in excellent agreement with experimental observations. It is widely assumed, however, that the SM is only a low energy approximation of …

Study of direct CP violation in B+- ---> J/psi K+- (pi+-) file decays

V M Abazov, Jinr Dubna, B. Abbott, /Oklahoma U. et autres

The authors present a search for direct CP violation in B{sup {+-}} {yields} J/{psi}K{sup {+-}}{pi}{sup {+-}} decays. The event sample is selected from 2.8 fb{sup -1} of p{bar p} collisions recorded by D0 experiment in Run II of the Fermilab Tevatron Collider. …
