50. Factorization and resummation of the heavy quark pair angular decorrelation

Dingyu Shao (Fudan University)

We present a comprehensive theoretical investigation of the angular decorrelation of heavy quark pairs in electron-positron ($e^+e^-$) and electron-proton ($ep$) collisions. Emphasizing the back-to-back limit in $e^+e^-$ collisions, we highlight the necessity of a Transverse Momentum Dependent (TMD) factorization and resummation theorem for heavy quark pair production. Our study introduces a...

The high energy (Regge) limit provides a playground for understanding all loop structures of scattering amplitudes, and plays an important role in the description of many phenomenologically relevant cross-sections. While well understood in the planar limit, the structure of non-planar corrections introduces many fascinating complexities, for which a general organizing principle is still...

51. Towards NLO-BFKL from Glauber-SCET

The high energy limit of QCD is a storehouse of rich phenomenology. In this limit, perturbative series receive logarithmic (small-$x$) enhancements associated with wide-rapidity separations necessitating their all-order resummation. However, reliably and comprehensively incorporating the NLL corrections associated with this limit consistent with collinear resummation and PDF factorization has...
