Small-x, Diffraction and Vector Mesons
We discuss diffractive production of open charm and bottom mesons at the LHC [1]. The differential cross sections for single- and central-diffractive mechanisms for c ̄c and b ̄b pair production are calculated in the framework of the Ingelman-Schlein model corrected for absorption effects. In this approach one assumes that the pomeron has a well defined partonic structure, and that the hard...

Small-x, Diffraction and Vector Mesons
ALICE has measured the coherent photo-nuclear production of $\rho^0$, J/$\psi$ and $\psi(2S)$ vector mesons at mid-rapidity in ultra-peripheral collisions of lead nuclei. These processes provide information on the gluon structure of the nuclear target at low Bjorken-$x$. The talk will cover the results from LHC Run1 data, as well as discuss the current status and prospects for analyses with...

Heavy Flavours (Charm, Beauty and Top)
J/Psi mesons are copiously produced at the LHC. Inspired by the Mueller Navelet jet studies, we propose to consider the production of a forward J/Psi accompanied by a backward jet. We make a feasibility study for this process and we compute the leading order differential cross section for such events in the BFKL framework.

Small-x, Diffraction and Vector Mesons
The amplitude for $\gamma p \to V p$, where $V$ is a $J/\psi$ or $\Upsilon$ ground state or excited
vector meson, is calculated in a pQCD $k_{T}$-factorization approach.
We use this amplitude to predict
the cross section for exclusive photoproduction of $J/\psi, psi', \Upsilon$ mesons in proton-proton collisions. Calculations are performed for a variety of unintegrated gluon...

Small-x, Diffraction and Vector Mesons
Measurements of open charm production are presented in diffractive deep inelastic scattering (5 < Q2 < 100 GeV2), based on HERA data recorded at √s = 319 GeV with an integrated luminosity of 281 pb-1. The event topology is given by ep → eXY, where the system X, containing at least one D(2010) meson, is separated from a leading
low-mass proton dissociative system Y by a large rapidity gap. The...
