+Jet Production with the Cambridge/Aachen Algorithm
K. Khelifa-Kerfa
We present fixed-order perturbative calculations up to four-loop order for a generic non-global QCD observable in hadron-hadron collisions. Specifically, we study the invariant-mas…
Clustering logarithms up to six loops
K. Khelifa-Kerfa
We compute the leading clustering (abelian non-global) logarithms, which arise in the distribution of non-global QCD observables when final-state partons are clustered using the $k…
Analytical structure of k clustering to any order
K. Khelifa-Kerfa
We present a general analytical expression for the fixed-order structure of the distribution of a generic non-global observable with the k jet algorithm at any perturbative ord…
Dijet azimuthal decorrelation in annihilation
Hana Benslama, Yazid Delenda, Kamel Khelifa-Kerfa
We examine non-global and clustering logarithms in the distribution of the azimuthal decorrelation between two jets in dijet events, where the jets are defined with …
Jet shapes in H/V boson + jet with clustering at hadron colliders
K. Khelifa-Kerfa, Y. Delenda, N. Ziani
We present analytical calculations of the distribution of non-global jet shapes in Higgs/vector boson + jet production at hadron colliders. Within the eikonal-limit framework and i…
Azimuthal decorrelation between a jet and a Z boson at hadron colliders
Hamza Bouaziz, Yazid Delenda, Kamel Khelifa-Kerfa
We revisit the azimuthal decorrelation between a jet and a boson produced at hadron colliders. Employing different recombination schemes for the jets leads to significantl…
QCD resummation for high-p jet shapes at hadron colliders
Kamel Khelifa-Kerfa
Exploiting the substructure of jets observed at the LHC to better understand and interpret the experimental data has recently been a very active area of research. In this thesis we…
Jet mass distribution in Higgs/vector boson + jet events at hadron colliders with clustering
Naima Ziani, Kamel Khelifa-Kerfa, Yazid Delenda
We address the issues of clustering and non-global logarithms for jet shapes in the process of production of a Higgs/vector boson associated with a single hard jet at hadron collid…
Eikonal amplitudes for three-hard legs processes at finite-N
Kamel Khelifa-Kerfa, Yazid Delenda
We extend our previous work on scattering amplitudes [1] to hadron collisions. We provide a general formalism for the computation of eikonal amplitudes squared for the radiation of…
Eikonal amplitudes and non-global logarithms from the BMS equation
Hana Benslama, Yazid Delenda, Kamel Khelifa-Kerfa +1
The Banfi-Marchesini-Smye (BMS) equation accounts for non-global logarithms to all orders in perturbation theory in the large-Nc approximation. We show that the squared amplitudes…

Yazid Delenda, Kamel Khelifa-Kerfa
We present a general formalism for computing the matrix-element squared for the emission of soft energy-ordered gluons beyond two loops in QCD perturbation theory at finite .…

Kamel Khelifa-Kerfa, Yazid Delenda
We present first calculations of QCD matrix-elements in perturbation theory at finite Nc beyond 2 loops in the eikonal approximation for e+ e- annihilation processes. For the emiss…

Non-global logarithms at finite Nc beyond leading order
Kamel Khelifa-Kerfa, Yazid Delenda
We analytically compute non-global logarithms at finite Nc fully up to 4 loops and partially at 5 loops, for the hemisphere mass distribution in e+e- to di-jets to leading logarith…
Resummation of clustering logarithms for non-global QCD observables
Yazid Delenda, Kamel Khelifa-Kerfa
We address the problem of resumming leading clustering logs in QCD jet observables defined using the k_t, CA and SISCone algorithms. We specifically choose the jet mass distributio…
On the resummation of clustering logarithms for non-global observables
Yazid Delenda, Kamel Khelifa-Kerfa
Clustering logs have been the subject of much study in recent literature. They are a class of large logs which arise for non-global jet-shape observables where final-state particle…
On jet mass distributions in Z+jet and dijet processes at the LHC
Mrinal Dasgupta, Kamel Khelifa-Kerfa, Simone Marzani +1
The mass distribution of jets produced in hard processes at the LHC plays an important role in several jet substructure related studies involving both Standard Model and BSM physic…
Non--global logs and clustering impact on jet mass with a jet veto distribution
Kamel Khelifa-Kerfa
There has recently been much interest in analytical computations of jet mass distributions with and without vetos on additional jet activity [1-6]. An important issue affecting suc…
Non-global logarithms and jet algorithms in high-pT jet shapes
Andrea Banfi, Mrinal Dasgupta, Kamel Khelifa-Kerfa +1
We consider jet-shape observables of the type proposed recently, where the shapes of one or more high-pT jets, produced in a multi-jet event with definite jet multiplicity, may be…
