This contribution focuses on the latest studies of heavy-flavour jets performed with ALICE detector. The measurements jet momentum fraction carried by D meson in pp collisions at s=5.02TeV and13TeV will be presented. comparison to POWHEG+PYTHIA shown. Moreover, first measurement LHC jet-momentum Λ+c baryon s=13TeV reported. Production also addressed charged tagged hadron decay electrons and bea...

The production of the excited charmed baryon doublet Lc * via fragmentation is studied. An analysis of the subsequent hadronic decays of the doublet within the framework of heavy hadron chiral perturbation theory produces expressions for both the angular distribution of the decay products and the polarization of the final state heavy baryon in terms of various nonperturbative fragmentation para...

The differential decay spectrum dΓ/dEedq 2 for the semileptonic decay of an unpolarized hadron containing a b-quark, and the decay spectrum dΓ/dEedq dcos θ for polarized Λb decay are computed to second order in the 1/mb expansion. Most of the 1/m 2 b corrections have a simple physical interpretation, which is discussed in detail. The implications of the results for the determination of Vub are ...

The large cross section for t t̄ production at the large hadron collider (LHC) and at any future hadron collider provides a high-statistics and relatively clean environment for a study of W boson properties: after tagging on a leptonic decay of one of the W s and the two b jets, an additional W still remains in the event. We study the prospect of making the first exclusive hadronic decay of a fu...

Detector R&D is advancing on many fronts of experimental particle physics, including efforts to produce massive, highly efficient, costeffective detectors for future neutrino experiments, for experiments requiring high bandwidth and high precision, such as hadron B factories, rare kaon decay experiments, and tau/charm factories, and for linear collider experiments. In recent years, the needs of...

In supersymmetry (SUSY) the flavor mixing between top-squark (stop) and charm-squark (scharm) induces the flavor-changing neutral-current (FCNC) stop decay t̃1 → cχ̃1. Searching for this decay serves as a probe of soft SUSY breaking parameters. Focusing on the stop pair production followed by the FCNC decay of one stop and the charge-current decay of the other stop, we investigate the potential o...

We present results of a large-scale simulation for the flavor non-singlet light hadron spectrum in quenched lattice QCD with the Wilson quark action. Hadron masses are calculated at four values of lattice spacing in the range a ≈ 0.1 – 0.05 fm on lattices with a physical extent of 3 fm at five quark masses corresponding to mπ/mρ ≈ 0.75 – 0.4. The calculated spectrum in the continuum limit shows...

It has been known for a long time that the cross section for bottom-quark b production at hadron collider energies exceeds theoretical expectations. An additional contribution from pairproduction of light gluinos g̃, of mass 12 to 16 GeV, with two-body decays into bottom quarks and light bottom squarks b̃, helps to obtain a b production rate in better agreement with data. The masses of the g̃ and ...

Strange and non-strange axial-vector meson radiative decays contribute to photon production in hadron gas. Oneand two-hadron radiative decay modes of b1(1235), a1(1260) andK1(1270) are studied. At 200 MeV temperature and for a narrow range in photon energies they contribute more to the net thermal photon production rate than πρ → πγ, ππ → ργ or ρ → ππγ. They provide significant contribution to ...

We investigate Higgs boson pair production at hadron colliders for Higgs boson masses mH<140 GeV and the rare decay of one of the two Higgs bosons. While in the standard model the number of events is quite low at the CERN Large Hadron Collider ~LHC!, a first, albeit not very precise, measurement of the Higgs boson self-coupling is possible in the gg→HH→bb̄gg channel. A luminosity-upgraded LHC co...
