We compute the energy dependence of the pt-integrated cross section of directly produced quarkonia in pp collisions at next-to-leading order within the nonrelativistic QCD framework. We treat the pt-integrated and the pt-differential cross sections as two different observables to investigate whether the CO LDMEs extracted from the fits of the pt-differential cross sections can predict the...

Fragmentation function of gluon to the spin-triplet color-singlet S-wave quarkonium has been calculated numerically earlier in 1992. However, the analytical result is absent because of the complex high dimensional integrals. With the development of the high-loop calculation, we consider to solve the problem with the IBP reduction. I will present our method and the final result, which is...

Proton nucleus collisions are expected to be unique tool to probe the physics of the initial state of ultra relativistic heavy ion collisions, without the presence of thermalisation and collective evolution of high energy density QCD matter. However, many observations related to the production of light and strange hadrons at low transverse momentum (pT) in p-Pb collisions at the LHC...

We study cold and hot nuclear matter effects on charmonium production in p+Pb collisions at$\sqrt{s_{NN}}$ = 5.02 TeV in a transport approach. As cold nuclear matter effects give almost the same modification on different $c\bar c$ states at the LHC energy, different nuclear modification factors of $J/\psi$ and $\psi^\prime$ indicate the existence of the hot medium. In forward rapidity, we can...

The coherent photon-nucleus interactions has been studied in detail at RHIC and LHC to probe the gluon distribution in nucleus at low Feynman $x$ via relativistic heavy-ion collisions. These kind of interactions are traditionally thought to only exist in ultra-peripheral collisions, where there is no hadronic interactions. Recently, a significant excess of J/$\psi$ yield at very low transverse...

We first study the doubly charmed baryon $\Xi_{cc}^+$ structure and yield in high energy nuclear collisions. Using hypericspherical expansion method, we solved the three-body Schr¨odinger equation including relativistic correction and calculate the yield of $\Xi_{cc}^+$ via coalescence mechanism. We find that, the $\Xi_{cc}^+$ created in heavy ion collision is like a quark-diquark state as a...

Two or more heavy quark-antiquark pairs can be produced in high energy collisions, not only because of increase of centre-of-mass energy, but also due to multiple parton scattering in case of hadron collisions. This will be a brief experimental overview on the double heavy production involving at least one quarkonium in the final state in $pp$ collisions at LHC, as well as in $e^{+} e^-$...

9. $\Upsilon+J/\psi$ and $J/\psi+J/\psi$ production at hadron colliders and double patron scatteringDr Yu-Jie Zhang (Beihang University)01/04/2017, 14:45
We present the first complete study of $\Upsilon$ and prompt $J/\psi$ production from single-parton scattering to the complete O($\alpha_s^6$) for color singlet contribution and including all leading SPS contributions. We find that the effective cross section characterizing the importance of double-parton scatterings is $\sigma_{eff}$≤8.2 mb at 68% confidence level from the D0 measurement. At...

We discuss the stability of tetraquarks systems made of two heavy quarks and two heavy antiquarks, with a potential model whose linear part is inspired by string dynamics.
At variance with some recent or less recent claims, we do not find binding for the double-charmonium or double-bottomonium cases. The string dynamics is, however, more favorable for (bcb̄c̄), i.e., a...
