چکیده

In the framework of the leading order of perturbative QCD and the nonrelativistic quark-diquark model of baryons we have obtained fragmentation function for c-quark to split into Ω ccc baryon. It is shown that at LHC one can expect 3.5 · 10 3 events with Ω ccc at p ⊥ > 5 GeV/c and |y| < 1 per year.

ترکش مزونهای سنگین در LHC

  Large Hadron Collider (LHC) at CERN will provide excellent opportunity to study the production and decay of heavy mesons and baryons with high statistics. We aim at the heavy mesons in this work and calculate their fragmentation functions consistent with this machine and present their total fragmentation probabilities and average fragmentation parameters.

تولید مزون‌های سنگین (S1)Bc در LHC و Tevatron Run II با در نظر گرفتن اسپین کوارک

 In this research, we have investigated the effect of spin orientation of quarks on the production of the Bc(1S) heavy mesons. We have calculated the fragmentation functions at initial scale µ° .Then we have modified to µ these fragmentation functions by using Altrali-Parisi equation. Also, we have calculated the transverse momentum distributions of the differential cross sections . Our results...

Meson B fragmentation function with consideration of mass corrections

Study of B meson (meson with the bottom quark flavor) in Large Hadron Collider (LHC) is of special importance so that the detector LHCb is devoted to investigate these types of mesons. For this reason, in this paper we will study the production process of this meson in a phenomenological approach using the experimental data from electron-positron annihilation. In this regards, we shall calculat...

Charmonium production at the LHC

The analyses of large transverse momentum charmonium production at the Tevatron have shown that fragmentation of gluons is an important production mechanism. We study large-pT charmonium production in pp collisions at the LHC, and find that due to the copious gluon production at this energy, the gluon fragmentation contribution completely overwhelms the fusion contribution and the charm quark f...

2 00 4 Production of B c mesons via fragmentation in the k T - factorization approach

Production of B c mesons via fragmentation in the k T-factorization approach Abstract In the framework of the k T-factorization approach we have calculated in the fragmentation model the p T-spectra of B c mesons at the energies of the Tevatron and the LHC Colliders and at the large p T domain. We compare the obtained results with the existing experimental data and with the predictions obtained...
