A bstractAn outstanding problem in QCD and jet physics is the factorization and resummation of logarithms that arise due to phase space constraints, so-called non-global logarithms (NGLs). In this paper, we show that NGLs can be factorized and resummed down to an unresolved infrared scale by making sufficiently many measurements on a jet or other restricted phase space region. Resummation is accomplished by renormalization group evolution of the objects in the factorization theorem and… 

Next-to-leading non-global logarithms in QCD

Abstract Non-global logarithms arise from the sensitivity of collider observables to soft radiation in limited angular regions of phase space. Their resummation to next-to-leading logarithmic (NLL)

Factorization and resummation for jet processes

A bstractFrom a detailed analysis of cone-jet cross sections in effective field theory, we obtain novel factorization theorems which separate the physics associated with different energy scales

Higher-order non-global logarithms from jet calculus

Abstract Non-global QCD observables are characterised by a sensitivity to the full angular distribution of soft radiation emitted coherently in hard scattering processes. This complexity poses a

Resumming double non-global logarithms in the evolution of a jet

A bstractWe consider the Banfi-Marchesini-Smye (BMS) equation which resums ‘non-global’ energy logarithms in the QCD evolution of the energy lost by a pair of jets via soft radiation at large angles.

Factorization for groomed jet substructure beyond the next-to-leading logarithm

A bstractJet grooming algorithms are widely used in experimental analyses at hadron colliders to remove contaminating radiation from within jets. While the algorithms perform a great service to the

Factorization and resummation for groomed multi-prong jet shapes

ABSTRACTObservables which distinguish boosted topologies from QCD jets are playing an increasingly important role at the Large Hadron Collider (LHC). These observables are often used in conjunction

Soft gluon evolution and non-global logarithms

A bstractWe consider soft-gluon evolution at the amplitude level. Our evolution algorithm applies to generic hard-scattering processes involving any number of coloured partons and we present a

Nonperturbative corrections to soft drop jet mass

Abstract We provide a quantum field theory based description of the nonperturbative effects from hadronization for soft drop groomed jet mass distributions using the soft- collinear effective

Electroweak logarithms in inclusive cross sections

A bstractWe develop the framework to perform all-orders resummation of electroweak logarithms of Q/M for inclusive scattering processes at energies Q much above the electroweak scale M. We calculate



Abelian non-global logarithms from soft gluon clustering

It is found that clustering logarithms can be naturally thought of as a class of non-global logarathms, which have traditionally been tied to non-Abelian correlations in soft gluon emission.

Factorization and Momentum-Space Resummation in Deep-Inelastic Scattering

Renormalization-group methods in soft-collinear effective theory are used to perform the resummation of large perturbative logarithms for deep-inelastic scattering in the threshold region x {yields}

A formalism for the systematic treatment of rapidity logarithms in Quantum Field Theory

A bstractMany observables in QCD rely upon the resummation of perturbation theory to retain predictive power. Resummation follows after one factorizes the cross section into the relevant modes. The

Resummation of jet-veto logarithms in hadronic processes containing jets

We derive a factorization theorem for production of an arbitrary number of colorsinglet particles accompanied by a xed number of jets at the LHC. The jets are dened with the standard antikT

We analytically and numerically study the effect of perturbative gluons emission on the “Filtering analysis”, which is part of a subjet analysis procedure proposed two years ago to possibly identify

Resummation of jet mass with and without a jet veto

Calculating the distribution of jet masses in high-energy collisions is challenging because fixed-order perturbation theory breaks down near the peak region, and because multiple scales complicate
