Heavy-flavour studies with a high-luminosity fixed-target experiment at the LHC
/ Trzeciak, Barbara Antonina (speaker) (Czech Technical University in Prague)
Extraction of the multi-TeV proton and lead LHC beams with a bent crystal or by using an internal gas target allows one to perform the most energetic fixed-target experiment ever. pp, pd and pA collisions at √sNN=115 GeV and Pbp and PbA collisions at √sNN=72 GeV can be studied with high precision and modern detection techniques over a broad rapidity range.
Using the LHCb and ALICE detectors in a fixed-target mode offers unprecedented possibilities to access heavy-flavour production in a new energy domain, half way between the SPS and nominal RHIC energies.
In this talk, we will review projection studies for quarkonium and open charm and beauty production with both detector set-ups used with various nuclear targets and the LHC lead beams.
We will also discuss prospects of novel observations, e.g. [...]

High luminosity fixed-target experiment at the LHC

By extracting the beam with a bent crystal or by using an internal gas target, the multi-TeV proton and lead LHC beams allow one to perform the most energetic fixed-target experiments ever and to study pp, pd and pA collisions at √sNN=115 GeV and Pbp and PbA collisions at √sNN=72 GeV with high precision and modern detection techniques. Such studies would address open questions in the domain of the nucleon and nucleus partonic structure at high-x, quark-gluon plasma and, by using longitudinally or transversally polarised targets, spin physics.

Spin Physics with a fixed-target experiment at the LHC
/ Echevarria, M.G. (INFN, Pavia) ; Brodsky, S.J. (SLAC) ; Cavoto, G. (INFN, Rome ; Rome U.) ; Da Silva, C. (Los Alamos) ; Donato, F. (INFN, Turin ; Turin U.) ; Ferreiro, E.G.

The multi-TeV proton and ion beams of the LHC would allow for the most energetic fixed-target experiment ever. In particular, pp, pd and pA collisions could be performed at √sNN = 115~GeV, as well as Pbp and PbA collisions at √sNN = 72~GeV, in a parasitic way by making use of the already existing LHCb and ALICE detectors in fixed-target mode.

Feasibility studies for quarkonium production at a fixed-target experiment using the LHC proton and lead beams (AFTER@LHC)
/ Massacrier, L. (Orsay, LAL ; Orsay, IPN) ; Trzeciak, B. (Prague, Tech. U.) ; Fleuret, F. (Ecole Polytechnique) ; Hadjidakis, C. (Orsay, IPN) ; Kikola, D. (Warsaw U. of Tech.) ; Lansberg, J.P. (Orsay, IPN) ; Shao, H. -S. (CERN)
Used in the fixed-target mode, the multi-TeV LHC proton and lead beams allow for studies of heavy-flavour hadroproduction with unprecedented precision at backward rapidities - far negative Feyman-x - using conventional detection techniques. At the nominal LHC energies, quarkonia can be studies in detail in p+p, p+d and p+A collisions at sqrt(s_NN) ~ 115 GeV as well as in Pb+p and Pb+A collisions at sqrt(s_NN) ~ 72 GeV with luminosities roughly equivalent to that of the collider mode, i.e. [...]

LHCb - Prospects of spontaneous Λ and ¯Λ transverse polarization measurements at LHCb
Reference: Poster-2023-1112
Created: 2023. -1 p
Creator(s): Nunez, Cynthia
Transverse Λ polarization observed over four decades ago contradicted expectations from early leading-order perturbative QCD calculations. Measurements of Λ polarization from unpolarized pp and pA collisions have been previously observed to increase as a function of xF and pT up to a few GeV range and approximately independent of beam energy. Recent studies have linked polarization to the process of hadronization, which describes how particular hadrons are formed from scattered quarks and gluons. The high energy of the LHC and the coverage and precision measurement possibilities from LHCb forward geometry are ideal for studying hyperon polarization as a function of both pT and xF . The status and prospects of Λ and Λ polarization measurements in pp, pPb, Pbp, and fixed-target pNe collisions at LHCb are presented
