Compatibility of global NPDF analyses of neutrino DIS and charged-lepton DIS data

K. Kovarik, I. Schienbein, F. I. Olness +5

The neutrino deep inelastic scattering (DIS) data is very interesting for global analyses of proton and nuclear parton distribution functions (PDFs) since they provide crucial info…

Impact of PDF uncertainties at large x on heavy boson production

L. T. Brady, A. Accardi, W. Melnitchouk +1

We explore the sensitivity of W and Z boson production in hadronic collisions to uncertainties in parton distribution functions (PDFs) at large x arising from uncertainties in nucl…

Towards W b bbar + j at NLO with an automatized approach to one-loop computations

Laura Reina, Thomas Schutzmeier

We present results for the O(alpha_s) virtual corrections to q g -> W b bbar q' obtained with a new automatized approach to the evaluation of one-loop amplitudes in terms of Feynma…

Interpreting LHC SUSY searches in the phenomenological MSSM

S. Sekmen, S. Kraml, J. Lykken +6

We interpret within the phenomenological MSSM (pMSSM) the results of SUSY searches published by the CMS collaboration based on the first ~1 fb^-1 of data taken during the 2011 LHC…

Effective Field Theory for a Heavy Majorana Fermion

Karoline Kopp, Takemichi Okui

We formulate an effective theory for systems containing a heavy Majorana fermion, such as bound states of a long-lived gluino. This "Majorana HQET" has the same degrees of freedom…

NLO QCD predictions for W+1 jet and W+2 jet production with at least one b jet at the 7 TeV LHC

F. Caola, J. M. Campbell, F. Febres Cordero +2

We calculate the production of a W boson in association with up to two jets including at least one b-jet to next-to-leading order (NLO) in QCD at the CERN Large Hadron Collider wit…

Z-Sum Approach to Loop Integrals using Taylor Expansion

Paulo A. Rottmann, Laura Reina

We study the applicability of the Z-Sum approach to multi-loop calculations with massive particles in perturbative quantum field theory. We systematically analyze the case of one-l…

Measuring Top Squark Interactions With The Standard Model Through Associated Production

Spencer Chang, Can Kilic, Takemichi Okui

A new particle's interactions can be measured at colliders, by observing its associated production with Standard Model particles. We focus on the case of a collider-stable right-ha…

Simplified Models for LHC New Physics Searches

Daniele Alves, Nima Arkani-Hamed, Sanjay Arora +92

This document proposes a collection of simplified models relevant to the design of new-physics searches at the LHC and the characterization of their results. Both ATLAS and CMS hav…

W b bbar production in POWHEG

Carlo Oleari, Laura Reina

We present an implementation of the next-to-leading order hadronic production of a W boson in association with a pair of massive bottom quarks in the framework of POWHEG, a method…

A unified, flavor symmetric explanation for the t-tbar asymmetry and Wjj excess at CDF

Ann E. Nelson, Takemichi Okui, Tuhin S. Roy

We present a simple, perturbative, and renormalizable model with a flavor symmetry which can explain both the t-tbar forward-backward asymmetry and the bump feature present in the…

Probing gluon and heavy-quark nuclear PDFs with photon + heavy quark production in pA collisions

T. Stavreva, I. Schienbein, F. Arleo +4

We present a detailed phenomenological study of direct photon production in association with a heavy-quark jet in pA collisions at the Relativistic Heavy Ion Collider (RHIC) and at…
