Open AccessThe Energy-Energy Correlation in the back-to-back limit at N3LO and N3LL′
We present the analytic formula for the Energy-Energy Correlation (EEC) in electron-positron annihilation computed in perturbative QCD to next-to-next-to-next-to-leading order (N3LO) in the back-to-back limit. In...

Open AccessTMD fragmentation functions at N3LO
We compute the unpolarized quark and gluon transverse-momentum dependent fragmentation functions (TMDFFs) at next-to-next-to-next-to-leading order (N3LO) in perturbative QCD. The calculation is based on a relatio...

Open AccessSubleading power resummation of rapidity logarithms: the energy-energy correlator in \( \mathcal{N} \) = 4 SYM
We derive and solve renormalization group equations that allow for the resummation of subleading power rapidity logarithms. Our equations involve operator mixing into a new class of operators, which we term th...

Open AccessFermionic Glauber operators and quark reggeization
We derive, in the framework of soft-collinear effective field theory (SCET), a Lagrangian describing the t-channel exchange of Glauber quarks in the Regge limit. The Glauber quarks are not dynamical, but are inco...
