Small-p&sub(T) Production of Polarised J/*q Mesons within the Soft Gluon Resummation Approach : Abstract / V.Saleev, K.Shilyaev // Физика элементарных частиц и атомного ядра. Письма. – 2025. – Т. 22, № 5. – P. 966. – URL: https://www1.jinr.ru/Pepan_letters/panl_2025_5/08_Saleev_ann.pdf.

In this work, we use the Soft Gluon Resummation approach as a noncollinear factorization model to describe polarisation of J/*q within NRQCD as a hadronization model. We extract nonperturbative LDME for octet color states of charmonium by fitting them to unpolarised J/*q production data of PHENIX and STAR collaborations at *%s = 200 GeV. We make prediction for an angular coefficient *l as a polarisation indicator for J/*q in the helicity frame and compare it with the PHENIX polarisation data.
