LHC Physics and Tevatron Results
We search for the Higgs boson produced in pp-collisions at sqrt{s} = 7 TeV with the ATLAS detector at the LHC. The searches are performed by using various decay channels such as H -> gamma gamma, WW, ZZ, tau tau and so on. The analysis of each final state is well performed, where main background contribution is understood in a data-driven technique, but we see no signifcant hint for the signal...

We present the results of searches for new physics in various topologies that lead to one or more isolated leptons, jets, and missing transverse energy in the final state. The searches are performed using 35 1/pb of data collected in 2010 by the CMS experiment at the LHC in pp-collisions at a center-of-mass energy of 7 TeV. Various data-driven techniques used to measure the Standard Model...

ALICE is the LHC experiment dedicated to the study of heavy-ion collisions. The main purpose of ALICE is to investigate the properties of a new state of deconfined nuclear matter, the quark–gluon plasma. Resonance production in proton-proton collisions is interesting in itself and important as a baseline for heavy-ion studies.
The study of short lived resonances allows the ...

FCNC decays of heavy flavour hadrons are highly sensitive to the effects of
physics beyond the Standard Model. Important observables include the branching
ratio of B_(s,d)->mu+mu- and D^0->mu+mu-, the angular distributions in the
decay B^0->K*mu+mu- and the lifetime distribution of Bs->phi gamma. First
results on some of these studies and related topics will be reported, using the

LHC Physics and Tevatron Results
The CMS experiment has measured the production of heavy flavored hadrons and jets at 7 TeV. A large range of inclusive and exclusive cross-section measurements (Quarkonia, charged and neutral B hadrons) as well as studies of B-B(bar) angular correlations were made and compared to theoretical predictions at LO and NLO precision. In this presentation we summarize these results.

Heavy flavour baryons containing one charm (beauty) quark with light flavour combinations are studied using the hypercentral approach. The considered potential is a combination of Coulombic, linear confining and harmonic oscillator terms. An improved form of the hyperfine interaction and isospin dependent quark potential is introduced. The ground state masses ( and ) of heavy baryons are...

We present recent BABAR results on lepton universality, and lepton
and baryon number conservation in Upsilon, B, charm and tau decays.
We also describe the results of direct searches for light new physics with BABAR. These include light pseudoscalar Higgs bosons, invisibly decaying dark matter candidates and hidden sector gauge and Higgs bosons.

The hadronization process turns partons produced in hard-scattering reactions into the physical, colorless, non-perturbative hadronic bound states detected in experiments. Within the standard framework, processes with an observed hadron in the final state can be described in terms of perturbative hard-scattering cross sections and certain non-perturbative but universal fragmentation functions,...

Since the LHC startup in 2009, the ATLAS inner tracker has played a central role in many ATLAS physics analyses. Rapid improvements in the calibration and alignment of the detector allowed it to reach nearly the nominal performance in the timespan of a few months. The tracking performance proved to be stable as the LHC luminosity increased by five orders of magnitude during the 2010 proton...

LHCb is performing a wide range of studies in the electroweak sector, in
soft-QCD and in jet physics. In many cases these measurements are unique and
complement well those of the other experiments at the LHC. This is because of
LHCb's forward geometry, low p_T acceptance and excellent particle
identification capabilities. Results and prospects will be presented based on
the 2010...

The scaling behavior of the v_2 at ultrarelativistic heavy ion collisions is considered as a signal of collective behavior of the partons in hot and/or dence hadronic matter [1-4]. The early results of CERN EMC [5-6] and JINR on the effect of limiting fragmentation of nuclei [7-9] were might be also explained through the collective behavior of the partons in the medium with extreme density....

in the B_s system, a precise determination of the unitarity triangle...

The MEG experiment is currently searching for the lepton-flavor-changing decay μ→eγ. Flavor mixing in the neutrino sector, which is implied by neutrino oscillations, leads to too small branching ratio of the μ→eγ in the Standard Model to be observed. Many extensions of the Standard Model such as Supersymmetric theories, however, bring the branching ratio of the decay within the reach of the...
