Jet shapes for boosted jet two-prong decays from first-principles

Mrinal Dasgupta, Lais Schunk, Gregory Soyez

Several boosted jet techniques use jet shape variables to discriminate the multi-pronged signal from Quantum Chromodynamics backgrounds. In this paper, we provide a first-principle…

The Quantum Critical Higgs

Brando Bellazzini, Csaba Csáki, Jay Hubisz +3

The appearance of the light Higgs boson at the LHC is difficult to explain, particularly in light of naturalness arguments in quantum field theory. However light scalars can appear…

Four-lepton production from photon-induced reactions in collisions at the LHC

Mateusz Dyndal, Laurent Schoeffel

The cross sections for the reaction in proton--proton collisions are calculated at the LHC energies. We show that the purely electroweak process $γγ\rightarro…

Evidence of sub-nucleonic degrees of freedom in J/ photoproduction in ultraperipheral collisions at the CERN Large Hadron Collider

E. Andrade-II, I. González, A. Deppman +1

We present calculations for the incoherent photoproduction of J/ vector mesons in ultra-peripheral heavy ion collisions (UPC) in terms of hadronic interactions. This study was c…

Resumming large higher-order corrections in non-linear QCD evolution

E. Iancu, J. D. Madrigal, A. H. Mueller +2

Linear and non-linear QCD evolutions at high energy suffer from severe issues related to convergence, due to higher order corrections enhanced by large double and single transverse…

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

Bin Wu

I give a self-contained review on radiative p_T-broadening and radiative energy loss of high-energy partons in QCD matter. The typical p_T^2 of high-energy partons receives a doubl…

Resurrecting the minimal renormalizable supersymmetric SU(5) model

Borut Bajc, Stéphane Lavignac, Timon Mede

It is a well-known fact that the minimal renormalizable supersymmetric SU(5) model is ruled out assuming superpartner masses of the order of a few TeV. Giving up this constraint an…

Generalised Parton Distributions: A Dyson-Schwinger approach for the pion

C. Mezrag

We compute the pion quark Generalised Parton Distribution H and quark Double Distributions in a coupled Bethe-Salpeter and Dyson-Schwinger approach in terms of quark flavors or iso…

Transverse momentum dependent (TMD) parton distribution functions: status and prospects

R. Angeles-Martinez, A. Bacchetta, I. I. Balitsky +34

We provide a concise overview on transverse momentum dependent (TMD) parton distribution functions, their application to topical issues in high-energy physics phenomenology, and th…

The Proton Mass and Scale-Invariant Hidden Local Symmetry for Compressed Baryonic Matter

Mannque Rho

I discuss how to access dense baryonic matter of compact stars by combining hidden local symmetry (HLS) of light-quark vector mesons with spontaneously broken scale invariance of a…

Collinearly-improved BK evolution meets the HERA data

E. Iancu, J. D. Madrigal, A. H. Mueller +2

In a previous publication, we have established a collinearly-improved version of the Balitsky-Kovchegov (BK) equation, which resums to all orders the radiative corrections enhanced…

New directional signatures from the non-relativistic effective field theory of dark matter

Bradley J. Kavanagh

The framework of non-relativistic effective field theory (NREFT) aims to generalise the standard analysis of direct detection experiments in terms of spin-dependent (SD) and spin-i…

Gluon Transport Equations with Condensate in the Small Angle Approximation

Jean-Paul Blaizot, Jinfeng Liao

We derive the set of kinetic equations that control the evolution of gluons in the presence of a condensate. We show that the dominant singularities remain logarithmic when the sca…
