Understanding the partonic energy loss in cold nuclear matter is crucial for a better interpretation of observations in future EIC experiments as well as the hot nuclear matter in high-energy collisions such as in LHC. Thus, the topic has received a lot of attention from the community over the past few decades. A clean probe to study the energy loss of partons in cold nuclear mater is nuclear...
The sPHENIX experiment is a new detector at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory. Designed for precision measurements of jet and heavy-flavor observables, sPHENIX provides precision vertexing, tracking, and electromagnetic and hadronic calorimetry in the central pseudorapidity region |eta| < 1.1 with full azimuthal coverage, at the full RHIC collision rate. In...
The sPHENIX experiment is a next-generation collider detector at the Relativistic Heavy Ion Collider (RHIC). The experiment includes a large acceptance, granular electromagnetic calorimeter and very high rate data acquisition plus trigger system. In the RHIC Run-2024, sPHENIX collected data from the collisions of transversely polarized protons at √s = 200 GeV using calorimeter-based,...
Understanding the internal structure of the nucleon remains one of the foremost goals in modern hadron physics. Transverse Momentum Dependent Parton Distribution Functions (TMD PDFs) provide a powerful framework for describing the three-dimensional partonic structure and internal dynamics of the nucleon. Semi-inclusive deep inelastic scattering measurements from HERMES and COMPASS have...
A polarized gaseous target, operated in combination with the high-energy and high-intensity LHC beams, has the potential to open new physics frontiers and to deepen our understanding of the strong interaction at the scale of confinement. Specifically, the LHCspin project aims to perform spin-physics studies in high-energy polarized fixed-target collisions using the LHCb detector. Being...
SpinQuest at Fermilab is a high-luminosity fixed-target experiment aimed at investigating the transverse momentum structure of the nucleon by measuring the Sivers function for light sea quarks and gluons. Using a 120 GeV unpolarized proton beam incident on transversely polarized ammonia (NH$_3$) and deuterated ammonia (ND$_3$) targets, the experiment seeks evidence of sea-quark orbital angular...
The SpinQuest (E1039) experiment at Fermilab is designed to explore the transverse single-spin asymmetry (TSSA), $A_N$, in $J/\psi$ production involving a transversely polarized solid-state NH$_3$/ND$_3$ target and a 120 GeV unpolarized proton beam. The target polarization is achieved using Dynamic Nuclear Polarization (DNP) in a 5 T magnetic field, driven by a 140 GHz Extended Interaction...
The SPD experiment will operate at one of the two interaction points of the NICA at JINR. The collider will deliver polarised beams for $pp$ and $dd$ collisions with center-of-mass energies up to $\sqrt{s} = 27\,\mathrm{GeV}$ and $\sqrt{s_{NN}} = 13.5\,\mathrm{GeV}$, respectively. The main objective of the experiment is to investigate both polarized and unpolarized gluonic structures of...
