Evidence for the decay B_s^0 --> D_s^(*)D_s^(*) and a measurement of Delta_Gamma_s^CP/Gamma_s
D0 Collaboration, V. M. Abazov
We search for the semi-inclusive process B_s^0 --> D_s^(*)D_s^(*) using 2.8 fb^-1 of ppbar collisions at s^(1/2) = 1.96 TeV recorded by the D0 detector operating at the Fermilab Te…
Evidence of WW+WZ production with lepton + jets final states in proton-antiproton collisions at sqrt(s)=1.96 TeV
D0 Collaboration, V. M. Abazov
We present the first evidence of WW+WZ production with lepton+jets final states at a hadron collider. The data correspond to 1.07 inverse femtobarns of integrated luminosity collec…
Kahler Independence of the G2-MSSM
Bobby S. Acharya, Konstantin Bobkov
The G2-MSSM is a model of particle physics coupled to moduli fields with interesting phenomenology both for colliders and astrophysical experiments. In this paper we consider a mor…
Precise measurement of the top quark mass from lepton+jets events at D0
D0 Collaboration, V. Abazov
We measure the mass of the top quark using top quark pair candidate events in the lepton+jets channel from data corresponding to 1 fb-1 of integrated luminosity collected by the D0…
Re-discovery of the top quark at the LHC and first measurements
Bobby S. Acharya, Francesca Cavallari, Gennaro Corcella +2
This paper describes the top quark physics measurements that can be performed with the first LHC data in the ATLAS and CMS experiments.
Monte Carlo generators for top quark physics at the LHC
Bobby S. Acharya, Francesca Cavallari, Gennaro Corcella +2
We review the main features of Monte Carlo generators for top quark phenomenology and present some results for t-tbar and single-top signals and backgrounds at the LHC.
Non-thermal Dark Matter and the Moduli Problem in String Frameworks
Bobby S. Acharya, Piyush Kumar, Konstantin Bobkov +3
We address the cosmological moduli/gravitino problems and the issue of too little thermal but excessive non-thermal dark matter from the decays of moduli. The main examples we stud…
Simultaneous measurement of the ratio B(t->Wb)/B(t->Wq) and the top quark pair production cross section with the D0 detector at sqrt(s)=1.96 TeV
D0 collaboration, V. Abazov
We present the first simultaneous measurement of the ratio of branching fractions, R=B(t->Wb)/B(t->Wq), with q being a d, s, or b quark, and the top quark pair production cross sec…
Simultaneous multi-wavelength observations of the TeV Blazar Mrk 421 during February - March 2003: X-ray and NIR correlated variability
Alok C. Gupta, B. S. Acharya, Debanjan Bose +2
In the present paper, we have reported the result of simultaneous multi-wavelength observations of the TeV blazar Mrk 421 during February March 2003. In this period, we have ob…
The -MSSM - An Theory motivated model of Particle Physics
Bobby S. Acharya, Konstantin Bobkov, Gordon L. Kane +2
We continue our study of the low energy implications of theory vacua on manifolds, undertaken in \cite{Acharya:2007rc,Acharya:2006ia}, where it was shown that the moduli…
