Di-J/ψ production at the Tevatron and the LHC
نویسندگان
چکیده
We briefly review recent results which we have obtained in the study of J/ψ-pair production at the Tevatron and the LHC. We claim that the existing data set from CMS and D0 point at a significant double-parton-scattering contribution with an effective cross section smaller than that for jet-related observables. We have also derived simple relations involving feed-down fractions from excited states which can help in disentangling the single from the double scatterings.

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...
متن کاملJa n 20 06 The Fermi motion contribution to J / ψ production at the Tevatron Run II
We show that the one order of magnitude discrepancy between the observed cross section and calculational results for J/ψ in the color singlet scenario may be improved partly by introducing the Fermi motion in its fragmentation production. We have used a light cone wave function to introduce the the Fermi motion. The results are compared to the CDF data and also predict the production of this st...
متن کاملFragmentation contributions to J/ψ production at the Tevatron and the LHC.
We compute leading-power fragmentation corrections to J/ψ production at the Tevatron and the LHC. We find that, when these corrections are combined with perturbative corrections through next-to-leading order in the strong coupling constant α(s), we obtain a good fit to high-p(T) cross section data from the CDF and CMS Collaborations. The fitted long-distance matrix elements lead to predictions ...
متن کاملDouble Diffractive Higgs and Di-photon Production at the Tevatron and LHC
We use the POMWIG Monte Carlo generator to predict the cross-sections for double diffractive higgs and di-photon production at the Tevatron and LHC. We find that the higgs production cross-section is too small to be observable at Tevatron energies, and even at the LHC observation would be difficult. Double diffractive di-photon production, however, should be observable within one year of Tevatr...
متن کاملCharmonium Production at Tevatron, Hera and Lhc *
Charmonia hadro-and photo-production are analyzed in the framework of the color-octet model taking into account higher-order effects induced by initial-state radiation of gluons. We argue that color-octet matrix elements obtained from Tevatron data might be reconciled with those extracted from HERA data on inelastic J/ψ photoproduction. Finally we estimate cross sections for events with muons f...
