We compute the ${\cal O}(\alpha_s^3)$ double-real-virtual (RRV) and double-virtual-real (VVR) soft contributions to the thrust/zero-jettiness event shape. The result clears up one of the most stubborn obstacles toward the complete ${\cal O}(\alpha_s^3)$ thrust soft function. The results presented here serve the key input to realize the next-to-next-to-next-to-leading logarithmic prime ...
The correlators of Wilson-line operators in non-abelian gauge theories are known to exponentiate, and their logarithms can be organised in terms of the collections of Feynman diagrams called Cwebs. The colour factors that appear in the logarithm correspond to completely connected diagrams and are determined by the web mixing matrices. In this talk we present several new concepts that we...
Beyond leading power there are interesting new phenomena that can be investigated in the realm of transverse momentum dependent (TMD) distribution functions, probed with processes like semi-inclusive DIS and Drell-Yan. In this talk I discuss the subleading power TMD factorization for these processes, including their dependence on novel distribution functions known as quark-gluon-quark ($qgq$)...
In this talk, I present the analysis of transverse momentum dependent (TMD) distributions of twist-three made in ref[2204.03856], focusing on their evolution equations. The starting point of discussion are the correlators with the definite TMD-twist. By considering suitable combinations of these correlators, I introduce physical TMD distribution of twist-three that can be used for practical...
The hot and dense medium of a quark gluon plasma (QGP) that can be recreated by ultrarelativistic
heavy ion collisions, can be examined only by indirect means, e.g. via highly energetic strongly interacting particles.
Studying the mechanisms of energy loss of partonic jets, i.e. collimated and highly energetic sprays of strongly interacting
particles provides an excellent means to access...
The thrust distribution associated with single-inclusive $e^+e^−$ annihilation (SIAthr), sensitive to the transverse momentum of the detected hadron with respect to the thrust axis, represents one of the most challenging and promising case where to extend the TMD factorization beyond the standard processes. At present days, its factorization properties have been studied through two different...
