"L=R" - as the Origin of Leptonic 'RPV'

Claudia Frugiuele, Thomas Gregoire, Piyush Kumar +1

A classification of phenomenologically interesting supersymmetric extensions of the Standard-Model with a symmetry is presented. Some of these are consistent with subsets…

Electroweak Phase Transition, Higgs Diphoton Rate, and New Heavy Fermions

Hooman Davoudiasl, Ian Lewis, Eduardo Ponton

We show that weak scale vector-like fermions with order one couplings to the Higgs can lead to a novel mechanism for a strongly first-order electroweak phase transition (EWPhT), th…

A running coupling explanation of the surprising transparency of the QGP at LHC

Alessandro Buzzatti, Miklos Gyulassy

The CUJET Monte Carlo Jet Energy loss model is applied to predict the jet flavor, centrality and density dependence of the nuclear modification factor at RHIC and LHC. Run…

Sudakov Resummation in Small-x Saturation Formalism

A. H. Mueller, Bo-Wen Xiao, Feng Yuan

Through an explicit calculation of massive scalar particle (e.g., Higgs boson) production in high energy pA collisions up to one-loop order, we demonstrate that the Sudakov-type lo…

"L=R" -- Lepton Number at the LHC

Claudia Frugiuele, Thomas Gregoire, Piyush Kumar +1

We perform a detailed study of a variety of LHC signals in supersymmetric models where lepton number is promoted to an (approximate) U(1)_R symmetry. Such a symmetry has interestin…

Falling Strings and Light Quark Jet Quenching at LHC

Andrej Ficnar, Jorge Noronha, Miklos Gyulassy

We explore phenomenological signatures of light quark jet quenching within the AdS/CFT correspondence. Numerical studies of the instantaneous energy loss of light quarks, modeled a…

TASI 2011: Four Lectures on TeV Scale Extra Dimensions

Eduardo Ponton

Compact spatial dimension at the TeV scale remain an intriguing possibility that is currently being tested at the LHC. We give an introductory review of extra-dimensional models an…

An overview of the CUJET model: Jet Flavor Tomography applied at RHIC and LHC

Alessandro Buzzatti, Miklos Gyulassy

Jet Flavor Tomography is a powerful tool used to probe the properties of Quark Gluon Plasma formed in heavy ion collisions at RHIC and LHC. A new Monte Carlo model of jet quenching…

pT-Broadening and production processes versus dipole/quadrupole amplitudes at next-to-leading order

A. H. Mueller, S. Munier

Through the systematic inspection of graphs in the framework of lightcone perturbation theory, we demonstrate that an identity between the evolution of pT-broadening amplitudes wit…

Color-neutral heavy particle production in nucleus-nucleus collisions in the quasi-classical approximation

Tseh Liou

We use a diagrammatic approach to study color-neutral heavy particle production in nucleus-nucleus collisions in a quasi-classical approximation without small- evolution. In ord…

Compactified String Theories -- Generic Predictions for Particle Physics

Bobby Samir Acharya, Gordon Kane, Piyush Kumar

In recent years it has been realized that in string/ theories compactified to four dimensions which satisfy cosmological constraints, it is possible to make some generic predict…

The Higgs as a Probe of Supersymmetric Extra Sectors

Jonathan J. Heckman, Piyush Kumar, Brian Wecht

We present a general method for calculating the leading contributions to h -> gg and h -> gamma gamma in models where the Higgs weakly mixes with a nearly supersymmetric extra sect…

Hyperon/meson ratios in rare high-multiplicity collisions at energies available at the Large Hadron Collider, and potential signatures for mini-quark-gluon plasma formation

V. Topor Pop, M. Gyulassy, J. Barrette +2

We use the framework of the HIJING/BB v2.0 model to simulate high-multiplicity (HM) collision events at the Large Hadron Collider (LHC) to study observables sensitive to poss…

Measuring Active-to-Sterile Neutrino Oscillations with Neutral Current Coherent Neutrino-Nucleus Scattering

A. J. Anderson, J. M. Conrad, E. Figueroa-Feliciano +5

Light sterile neutrinos have been introduced as an explanation for a number of oscillation signals at eV. Neutrino oscillations at relatively short baselines prov…

Jet Substructure at the Tevatron and LHC: New results, new tools, new benchmarks

A. Altheimer, S. Arora, L. Asquith +68

In this report we review recent theoretical progress and the latest experimental results in jet substructure from the Tevatron and the LHC. We review the status of and outlook for…
