Three-Prong Distribution of Massive Narrow QCD Jets
Matan Field, Guy Gur-Ari, David A. Kosower +2
We study the planar-flow distributions of narrow, highly boosted, massive QCD jets. Using the factorization properties of QCD in the collinear limit, we compute the planar-flow jet…
Effect of quark masses on the QCD presssure in a strong magnetic background
Jean-Paul Blaizot, Eduardo S. Fraga, Leticia F. Palhares
We compute the two-loop contribution to the QCD pressure in a strong magnetic background, for arbitrary quark masses. We show that, for very large fields, the chiral limit is trivi…
Color Glass Condensate and Glasma
F. Gelis
We review the Color Glass Condensate effective theory, that describes the gluon content of a high energy hadron or nucleus, in the saturation regime. The emphasis is put on applica…
Pileup subtraction for jet shapes
Gregory Soyez, Gavin P. Salam, Jihun Kim +2
Jet shapes have the potential to play a role in many LHC analyses, for example in quark-gluon discrimination or jet substructure analyses for hadronic decays of boosted heavy objec…
New picture of jet quenching dictated by color coherence
Jorge Casalderrey-Solana, Yacine Mehtar-Tani, Carlos A. Salgado +1
We propose a new description of the jet quenching phenomenon observed in nuclear collisions at high energies in which coherent parton branching plays a central role. This picture i…
Next-to-Leading Order correction to inclusive particle spectra in the Color Glass Condensate framework
F. Gelis, J. Laidet
In [arXiv:0804.2630], we have analyzed the leading logarithms of energy that appear in the inclusive spectrum of gluons produced in heavy ion collisions, calculated in the Color Gl…
Dynamical entropy of dense QCD states
Robi Peschanski
We discuss dense states of QCD matter formed in high-energy hadronic and heavy-ion collisions from the point of view of statistical physics of non-equilibrium processes. For this s…
Robust Determination of the Higgs Couplings: Power to the Data
Tyler Corbett, O. J. P. Eboli, J. Gonzalez-Fraile +1
We study the indirect effects of new physics on the phenomenology of the recently discovered "Higgs-like" particle. In a model independent framework these effects can be parametriz…
Thermalization and Bose-Einstein Condensation in Overpopulated Glasma
Jean-Paul Blaizot, Francois Gelis, Jinfeng Liao +2
We report recent progress on understanding the thermalization of the quark-gluon plasma during the early stage in a heavy ion collision. The initially high overpopulation in the fa…
Antenna Showers with Hadronic Initial States
M. Ritzmann, D. A. Kosower, P. Skands
We present an antenna shower formalism including contributions from initial-state partons and corresponding backwards evolution. We give a set of phase-space maps and antenna funct…
Can New Colored Particles Illuminate the Higgs?
Enrico Bertuzzo, Pedro A. N. Machado, Renata Zukanovich Funchal
We analyze the behavior of Higgs to diphoton rate and Higgs gluon-gluon production cross section in minimal extensions of the Standard Model comprising new colored vector-like ferm…
Universality of multi-particle production in QCD at high energies
Fabio Dominguez, Cyrille Marquet, Anna M. Stasto +1
By studying the color structure of multi-particle production processes in p+A-type (dilute-dense) collisions, we find that higher-point functions beyond typical dipoles and quadrup…
Pushing the SUSY Higgs mass towards 125 GeV with a color adjoint
Gautam Bhattacharyya, Tirtha Sankar Ray
We show that inclusion of a TeV scale chiral superfield transforming in the adjoint representation of the color SU(3) to the MSSM particle content modifies the renormalization grou…
Jet Fragmentation Function Moments in Heavy Ion Collisions
Matteo Cacciari, Paloma Quiroga-Arias, Gavin P. Salam +1
The nature of a jet's fragmentation in heavy-ion collisions has the potential to cast light on the mechanism of jet quenching. However the presence of the huge underlying event com…
Coherence and broadening effects in medium induced gluon radiation
Néstor Armesto, Hao Ma, Mauricio Martinez +2
Interferences between different emitters in the multi-parton shower is the building block of QCD jet physics in vacuum. The presence of a hot medium made of quarks and gluons is ex…
Medium-induced gluon branching
Jean-Paul Blaizot, Fabio Dominguez, Edmond Iancu +1
We study the evolution of an energetic jet which radiates gluons while propagating through a dense QCD medium modeled as a random distribution of color sources. Motivated by the he…
Does Taste like vanilla New Physics?
Leandro G. Almeida, Enrico Bertuzzo, Pedro A. N. Machado +1
We analyse the interplay between the Higgs to diphoton rate and electroweak precision measurements contraints in extensions of the Standard Model with new uncolored charged fermion…
PAMELA and FERMI-LAT limits on the neutralino-chargino mass degeneracy
Genevieve Belanger, Celine Boehm, Marco Cirelli +2
Searches for Dark Matter (DM) particles with indirect detection techniques have reached important milestones with the precise measurements of the anti-proton and gamma-ray spectra,…
Antenna subtraction at NNLO with hadronic initial states: double real initial-initial configurations
Aude Gehrmann-De Ridder, Thomas Gehrmann, Mathias Ritzmann
The antenna subtraction method handles real radiation contributions in higher order corrections to jet observables. The method is based on antenna functions, which encapsulate all…
Potential of a Neutrino Detector in the ANDES Underground Laboratory for Geophysics and Astrophysics of Neutrinos
P. A. N. Machado, T. Mühlbeier, H. Nunokawa +1
The construction of the Agua Negra tunnels that will link Argentina and Chile under the Andes, the world longest mountain range, opens the possibility to build the first deep under…
Constraining anomalous Higgs interactions
Tyler Corbett, O. J. P. Eboli, J. Gonzalez-Fraile +1
The recently announced Higgs discovery marks the dawn of the direct probing of the electroweak symmetry breaking sector. Sorting out the dynamics responsible for electroweak symmet…
Interference between initial and final state radiation in a QCD medium
Néstor Armesto, Hao Ma, Mauricio Martinez +2
We investigate the color coherence pattern between initial and final state radiation in the presence of a QCD medium. We derive the medium-induced gluon spectrum of an "asymptotic"…
Missing Energy and Jets for Supersymmetry Searches
Z. Bern, G. Diana, L. J. Dixon +6
We extend our investigation of backgrounds to new physics signals, following CMS's data-driven search for supersymmetry at the LHC. The aim is to use different sets of cuts in gamm…

F. de Campos, O. J. P. Éboli, M. B. Magro +5
Supersymmetric models with bilinear R-parity violation (BRPV) can account for the observed neutrino masses and mixing parameters indicated by neutrino oscillation data. We consider…
