The goal of LHCspin is to develop, in the next few years, innovative solutions and cutting-edge technologies to access spin physics in high-energy polarized fixed-target collisions, by exploring a unique kinematic regime given by the LHC beam and by exploiting new probes. This ambitious task poses its basis on the recent installation of SMOG2, the unpolarized gas target in front of the LHCb...
We present a calculation of the azimuthal asymmetries in back-to-back production of $J/\psi - \mathrm{jet}$ and $J/\psi-\gamma$ in eP collision. We use NRQCD to estimate the $J/\psi$ production, and assume TMD factorization for the back-to-back kinematics. We show that these asymmetries will be useful for probing the the gluon TMDs, like the linearly polarizaed gluon TMD, in unpolarized...
The near threshold region of heavy quarkonium has received a lot of attention with possible applications to a wide breadth of physics. I will discuss the recent JPAC analysis of new Jefferson Lab data from the GlueX and Jpsi-007 experiments. I will discuss the still wide array of physics scenarios that may underpin the near threshold data including strong coupled channel effects to open charm...
