On the mass and decay constant of K-2*(1430) tensor meson
(IOP Publishing, 2010-02)
The mass and decay constant of the ground state strange tensor meson K-2* (1430) with I(J(P)) = 1/2(2(+)) are calculated using the QCD sum rules method. The results are consistent with the experimental data. It is found ...
Measurement of event shapes at large momentum transfer with the ATLAS detector in pp collisions at root s=7 TeV
A measurement of event shape variables is presented for large momentum transfer proton-proton collisions using the ATLAS detector at the Large Hadron Collider. Six event shape variables calculated using hadronic jets are ...
FCNC transitions of Lambda(b,c) to nucleon in SM
(IOP Publishing, 2010-11)
We provide a comprehensive study of semileptonic flavor-changing neutral current transitions for Lambda(b) -> nl(+) l(-) and Lambda(c) -> pl(+) l(-) in the context of light cone QCD sum rules. Using the most general form ...
Investigation of P-wave scalar and S-wave pseudo-scalar charmonia semileptonic transitions to the D-s(D) meson in QCD
(IOP Publishing, 2010-07)
In this work, the semileptonic decays of the scalar charmonium state X-c0 and the pseudo scalar charmonia states eta(c)(1s) and eta(c)(2s) into D-s and D mesons are analyzed. The form factors of the transitions X-c0 -> ...
Measurement of jet shapes in top-quark pair events at root s=7 TeV using the ATLAS detector
A measurement of jet shapes in top-quark pair events using 1.8 fb(-1) of pp collision data recorded by the ATLAS detector at the LHC is presented. Samples of top-quark pair events are selected in both the single-lepton and ...
Observation and measurements of the production of prompt and non-prompt J/psi mesons in association with a z boson in pp collisions at root s=8 Tev with the ATLAS detector
The production of a Z boson in association with a J/psi meson in proton-proton collisions probes the production mechanisms of quarkonium and heavy flavour in association with vector bosons, and allows studies of multiple ...
