New data form the LHC proton-lead run shall be available soon. Wether it is compatible with previous nuclear data or not should be done by its inclusion in a time consuming full global fit of initial state nuclear effects. One possibility to avoid such a procedure is to employ the reweighting technique, already used by the NNPDF collaboration. In this work we apply the reweighting to the study...

ALICE, the dedicated heavy-ion detector at the LHC, observed J/psi suppression in Pb-Pb collisions at sqrt(s_NN)=2.76 TeV. The interpretation of that observation can be helped by performing a similar measurement in p-Pb collisions, where only cold nuclear matter effects are relevant. In this talk we will show results on inclusive J/psi production in p-Pb collisions at sqrt(s_NN)=5.02 TeV in...

The recent pPb run at 5 TeV which took place at CERN LHC provides exciting measurements of the Nuclear Matter (NM) effects, especially for the heavy quark and quarkonium sectors. The comparison of the experimental results to the phenomenological inputs at this unprecedented energy is eagerly expected.
We study the NM effects on J/psi [1], Upsilon [2] and open beauty [3] production. We...

In hadron collisions at the LHC, charm quarks are produced almost exclusively in initial hard parton scattering processes because of their large mass. Therefore, charm hadrons are excellent probes to study the dynamics of the hot and dense Quark-Gluon Plasma (QGP) produced in such collisions. For the quantitative interpretation of measurements in heavy-ion collisions it is mandatory to...

At LHC energies heavy-ion collisions produce a high energy density QCD matter. One important probe of this matter are heavy-flavour quarks, as they are primarily produced in the early stage of the collision through initial hard scatterings, thus experiencing the full evolution of the system. In ALICE heavy-flavour production is studied in pp, p-Pb, and Pb-Pb collisions through the measurement...

We outline the physics opportunities [1] which are offered by a next generation and multi-purpose fixed-target experiment exploiting the LHC beams extracted by a bent crystal. This mature extraction technique offers an ideal way to obtain a clean and very collimated high-energy beam, without altering at all the performance of the LHC [2,3,4]. The multi-TeV LHC beams grant the most energetic...
