Description

Single inclusive hadron production in Deep Inelastic Scattering (SIDIS) is one of the most promising processes in which to look for signatures of color glass condensate (CGC), a dense state of gluons in a proton/nucleus that is believed to exist at small $x$. While there have been strong hints of CGC dynamics observed at HERA, RHIC and the LHC, an unambiguous interpretation has eluded the community due to presence of several important non-CGC effects. One of the most important such effects is Sudakov suppression due to radiation of soft gluons. Here we present our calculation of Sudakov double logs in SIDIS and report on the progress made toward calculation of Sudakov single logs, a completion of which would go a long way toward establishing, quantitatively and for the first time, the relative significance of Sudakov effects vs Saturation dynamics in different kinematics at the future EIC.
