Description
We present recent progress in precision TMD physics, focusing on three key developments. First, we provide the N3LO twist-2 matching for polarized TMDs, along with the complete set of N3LO polarized DGLAP evolution kernels for quark (gluon) helicity and quark transversity distributions. Second, we achieve N3LL accuracy in predictions for the SIDIS $q_T$ spectrum, the lepton-hadron transverse momentum imbalance, and semi-inclusive Transverse Energy–Energy Correlators (TEEC). Finally, we introduce an exponential regulator in SCET$_G$ and Lipatov’s Reggeon Field Theory, thereby enabling precise studies of quark–gluon reggeization, the dynamics of small-$x$ TMDs, and TMD factorization violation.
