Bc -> J/psi(Bs,Bs*)+ n pi Decays
A. V. Berezhnoy, A. K. Likhoded, A. V. Luchinsky
The Bc -> J/psi(Bs,Bs*)+ n pi decay amplitudes are calculated in the frame work of factorization model, which allows to represent this processes as Bc decay into J/psi Bs+W* follow…
Tetraquarks composed of 4 heavy quarks
A. V. Berezhnoy, A. V. Luchinsky, A. A. Novoselov
In the current work spectroscopy and possibility of observation at the LHC of tetraquarks composed of 4 heavy quarks is discussed. Tetraquarks concerned are T_{4c}=[cc][cc]$, T_{4b…
Double J/psi-meson Production at LHC and 4c-tetraquark state
A. V. Berezhnoy, A. K. Likhoded, A. V. Luchinsky +1
The article is devoted to double J/psi-meson production at LHC. Theoretical predictions for pp -> 2J/psi+X cross section at sqrt{s}=7 TeV for different kinematical restrictions are…
