Extrapolating W-Associated Jet-Production Ratios at the LHC

Z. Bern, L. J. Dixon, F. Febres Cordero +4

Electroweak vector-boson production, accompanied by multiple jets, is an important background to searches for physics beyond the Standard Model. A precise and quantitative understa…

The LBNO long-baseline oscillation sensitivities with two conventional neutrino beams at different baselines

LBNO Collaboration, S. K. Agarwalla, L. Agostino +157

The proposed Long Baseline Neutrino Observatory (LBNO) initially consists of kton liquid double phase TPC complemented by a magnetised iron calorimeter, to be installed a…

Optimised sensitivity to leptonic CP violation from spectral information: the LBNO case at 2300 km baseline

LBNO Collaboration, S. K. Agarwalla, L. Agostino +157

One of the main goals of the Long Baseline Neutrino Observatory (LBNO) is to study the behaviour (spectral information) of the electron neutrino and antineutrino appearance p…

Particle Production with Rapidity Correlations in Proton-Nucleus Collisions

E. Iancu, J. D. Madrigal, D. N. Triantafyllopoulos

We illustrate how a generalization of the JIMWLK formalism which treats independently the direct and complex conjugate amplitudes can be used to describe semi-inclusive multipartic…

Light-by-light scattering with intact protons at the LHC: from Standard Model to New Physics

Sylvain Fichet, Gero von Gersdorff, Bruno Lenzi +2

We discuss the discovery potential of light-by-light scattering at the Large Hadron Collider (LHC), induced by the Standard Model (SM) and by new exotic charged particles. Our simu…

The role of finite-size effects on the spectrum of equivalent photons in proton-proton collisions at the LHC

Mateusz Dyndal, Laurent Schoeffel

Photon-photon interactions represent an important class of physics processes at the LHC, where quasi-real photons are emitted by both colliding protons. These reactions can result…

NLO Vertex for a Forward Jet plus a Rapidity Gap at High Energies

Martin Hentschinski, José Daniel Madrigal Martínez, Beatrice Murdaca +1

We present the calculation of the forward jet vertex associated to a rapidity gap (coupling of a hard pomeron to the jet) in the BFKL formalism at next-to-leading order (NLO). Real…

The Gluon-Induced Mueller-Tang Jet Impact Factor at Next-to-Leading Order

Martin Hentschinski, José Daniel Madrigal Martínez, Beatrice Murdaca +1

We complete the computation of the Mueller-Tang jet impact factor at next-to-leading order (NLO) initiated in arXiv:1406.5625 and presented in arXiv:1404.2937 by computing the real…

Angular distribution of medium-induced QCD cascades

Jean-Paul Blaizot, Leonard Fister, Yacine Mehtar-Tani

We provide a complete description of the angular distribution of gluons in a medium-induced QCD cascade. We identify two components in the distribution, a soft component dominated…

Massive renormalization scheme and perturbation theory at finite temperature

Jean-Paul Blaizot, Nicolas Wschebor

We argue that the choice of an appropriate, massive, renormalization scheme can greatly improve the apparent convergence of perturbation theory at finite temperature. This is illus…

pair production in proton-proton collisions: small missing terms

Marta Luszczak, Antoni Szczurek, Christophe Royon

production is one of the golden channels for testing the Standard Model as well for searches beyond the Standard Model. We discuss many new subleading processes for inclu…

Properties of the Boltzmann equation in the classical approximation

Thomas Epelbaum, Francois Gelis, Naoto Tanji +1

We study the Boltzmann equation with elastic point-like scalar interactions in two different versions of the the classical approximation. Although solving numerically the Boltzmann…

The three-loop cusp anomalous dimension in QCD

Andrey Grozin, Johannes M. Henn, Gregory P. Korchemsky +1

We present the full analytic result for the three-loop angle-dependent cusp anomalous dimension in QCD. With this result, infrared divergences of planar scattering processes with m…

Radiative energy loss and radiative p_T-broadening of high-energy partons in QCD matter

Bin Wu

We study the connection between radiative energy loss and radiative p_T-broadening of a high-energy quark or gluon passing through QCD matter. The generalized Baier-Dokshitzer-Muel…

Antiproton constraints on the GeV gamma-ray excess: a comprehensive analysis

Marco Cirelli, Daniele Gaggero, Gaëlle Giesen +2

A GeV gamma-ray excess has possibly been individuated in Fermi-LAT data from the Galactic Center and interpreted in terms of Dark Matter (DM) annihilations, either in hadronic (ess…

Leading large-x logarithms of the quark-gluon contributions to inclusive Higgs-boson and lepton-pair production

N. A. Lo Presti, A. A. Almasy, A. Vogt

We present all-order expressions for the leading double-logarithmic threshold contributions to the quark-gluon coefficient functions for inclusive Higgs-boson production in the hea…

Wino-like Minimal Dark Matter and future colliders

Marco Cirelli, Filippo Sala, Marco Taoso

We extend the Standard Model with an EW fermion triplet, stable thanks to one of the accidental symmetries already present in the theory. On top of being a potential Dark Matter ca…

Connecting neutrino physics with dark matter

Massimiliano Lattanzi, Roberto A. Lineros, Marco Taoso

The origin of neutrino masses and the nature of dark matter are two of the most pressing open questions of the modern astro-particle physics. We consider here the possibility that…

On the use of charged-track information to subtract neutral pileup
