NNLL resummation for projected three-point energy correlator [PDF]
Journal of High Energy Physics, 2023 The projected energy correlator measures the energy deposited in multiple detectors as a function of the largest angular distance xL = (1 − cos χL)/2 between detectors.

Energy correlators on tracks: resummation and non-perturbative effects [PDF]
Journal of High Energy Physics, 2023 Energy correlators measured inside high-energy jets at hadron colliders have recently been demonstrated to provide a new window into both perturbative and non-perturbative Quantum Chromodynamics.

Stop comparing resummation methods [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2023 I argue that the consistency of any resummation method can be established if the method follows a power counting derived from a hierarchy of scales. I.e., whether it encodes a top-down effective field theory.

Resummation of Next-to-Leading Nonglobal Logarithms at the LHC. [PDF]
Physical Review Letters, 2023 In cross sections with angular cuts, an intricate pattern of enhanced higher-order corrections known as nonglobal logarithms arises. The leading logarithmic terms were computed numerically two decades ago, but the resummation of subleading nonglobal ...

Combining thermal resummation and gauge invariance for electroweak phase transition [PDF]
Journal of High Energy Physics, 2022 For computing thermodynamics of the electroweak phase transition, we discuss a minimal approach that reconciles both gauge invariance and thermal resummation.

Next-to-leading power endpoint factorization and resummation for off-diagonal “gluon” thrust [PDF]
Journal of High Energy Physics, 2022 The lack of convergence of the convolution integrals appearing in next-to-leading-power (NLP) factorization theorems prevents the applications of existing methods to resum power-suppressed large logarithmic corrections in collider physics.

Threshold Resummation for the Production of Four Top Quarks at the LHC. [PDF]
Physical Review Letters, 2022 We compute the total cross section for tt[over ¯]tt[over ¯] production at next-to-leading logarithmic (NLL^{'}) accuracy. This is the first time resummation is performed for a hadron-collider process with four colored particles in the final state.

Global QCD Analysis of Pion Parton Distributions with Threshold Resummation. [PDF]
Physical Review Letters, 2021 We perform the first global QCD analysis of pion valence, sea quark, and gluon distributions within a Bayesian Monte Carlo framework with threshold resummation on Drell-Yan cross sections at next-to-leading log accuracy.

Fiducial Drell-Yan production at the LHC improved by transverse-momentum resummation at N$^4$LL+N$^3$LO [PDF]
, 2022 Drell-Yan production is one of the precision cornerstones of the LHC , serving as calibration for measurements such as the W -boson mass. Its extreme precision at the level of 1% challenges theory predictions at the highest level.

Drell–Yan lepton-pair production: qT resummation at N3LL accuracy and fiducial cross sections at N3LO [PDF]
Physical Review D, 2021 We present high-accuracy QCD predictions for the transverse-momentum ($q_T$) distribution and fiducial cross sections of Drell-Yan lepton pairs produced in hadronic collisions.
