Same-sign WW production in proton-nucleus collisions at the LHC as a signal for double parton scattering

David d'Enterria, Alexander M. Snigirev

The production of same-sign W-boson pairs from double parton scatterings (DPS) in proton-lead (p-Pb) collisions at the CERN Large Hadron Collider is studied. The signal and backgro…

Higgs diphoton rate enhancement from supersymmetric physics beyond the MSSM

Marcus Berg, Igor Buchberger, D. M. Ghilencea +1

We show that supersymmetric "new physics" beyond the MSSM can naturally accommodate a Higgs mass near 126 GeV and enhance the signal rate in the Higgs to diphoton channel, while th…

Superradiance or total reflection?

András László, István Rácz

Numerical evolution of massless scalar fields on Kerr background is studied. The initial data specifications are chosen to have compact support separated from the ergoregion and to…

Conceptual Design of a New Large Superconducting Toroid for IAXO, the New International AXion Observatory

I. Shilon, A. Dudarev, H. Silva +1

The International AXion Observatory (IAXO) will incorporate a new generation detector for axions, a hypothetical particle, which was postulated to solve one of the puzzles arising…

The Higgs Mass beyond the CMSSM

John Ellis, Feng Luo, Keith A. Olive +1

The apparent discovery of a Higgs boson with mass ~125 GeV has had a significant impact on the constrained minimal supersymmetric extension of the Standard Model in which the scala…

Data driving the top quark forward--backward asymmetry with a lepton-based handle

Adam Falkowski, Michelangelo L. Mangano, Adam Martin +2

We propose that, within the standard model, the correlation between the forward--backward asymmetry and the corresponding lepton-based asymmetry -- a…

Multi Higgs and Vector boson production beyond the Standard Model

A. Belyaev, A. C. A. Oliveira, R. Rosenfeld +1

If the electroweak symmetry breaking is originated from a strongly coupled sector, as for instance in composite Higgs models, the Higgs boson couplings can deviate from their Stand…

Field-theoretic Methods in Strongly-Coupled Models of General Gauge Mediation

Jean-François Fortin, Andreas Stergiou

An often-exploited feature of the operator product expansion (OPE) is that it incorporates a splitting of ultraviolet and infrared physics. In this paper we use this feature of the…

Momentum Broadening in Weakly Coupled Quark-Gluon Plasma (with a view to finding the quasiparticles within liquid quark-gluon plasma)

Francesco D'Eramo, Mindaugas Lekaveckas, Hong Liu +1

We calculate P(k_\perp), the probability distribution for an energetic parton that propagates for a distance L through a medium without radiating to pick up transverse momentum k_\…

Open questions in QCD at high parton density

Cyrille Marquet

I present the state of our understanding of the QCD dynamics at play in the parton saturation regime of nuclear wave functions. I explain what are the biggest open questions in the…

Light non-degenerate squarks at the LHC

Rakhi Mahbubani, Michele Papucci, Gilad Perez +2

Experimental bounds on squarks of the first two generations assume their masses to be eightfold degenerate, and consequently constrain them to be heavier than ~ 1.4 TeV when the gl…

Urs Achim Wiedemann

The two arguably most generic phenomena seen in ultra-relativistic heavy ion collisions are the flow of essentially all soft hadronic observables and the quenching of essentially a…
