Prompt production of J / in the soft gluon resummation approach using the ICEM

In the article, we study prompt J/𝜓 production at small transverse momentum within the Transverse Momentum Dependent (TMD) factorization. The Soft Gluon Resummation (SGR) approach is used for modelling of TMD PDFs. The hadronization process of heavy charm quarks is described with the Improved Color Evaporation model (ICEM). In order to obtain spectra of J/𝜓 at the arbitrary transverse momenta, fixed-order calculations within the collinear parton model (CPM) are also applied and further matched
