Gravitino Dark Matter
Wilfried Buchmuller
Gravitino dark matter, together with thermal leptogenesis, implies an upper bound on the masses of superparticles. In the case of broken R-parity the constraints from primordial nu…
Cosmic-Ray Signatures of Dark Matter Decay
David Tran
In light of recent observations of an anomalous excess of high-energy positrons and electrons by the PAMELA and Fermi LAT experiments, we investigate exotic cosmic-ray signatures i…
String Model Building
Stuart Raby
In this talk I review some recent progress in heterotic and F theory model building. I then consider work in progress attempting to find the F theory dual to a class of heterotic o…
Mixed Axion/Axino Dark Matter in mSUGRA and Yukawa-unified SUSY
Heaya Ann Summy
Axion/axino dark matter (DM) is explored in the minimal supergravity (mSUGRA) and Yukawa-unified supersymmetric grand-unified theory (SUSY GUT) models with surprising results. For…
Fermion mass hierarchy and new physics at the TeV scale
S. Nandi
In this talk, I present a new framework to understand the long-standing fermion mass hierarchy puzzle. We extend the Standard Model gauge symmetry by an extra local U(1)_S symmetry…
CP Violating Asymmetry in Stop Decay into Bottom and Chargino
Sebastian M. R. Frank, Helmut Eberl
In the MSSM with complex parameters, loop corrections to the decay of a stop into a bottom quark and a chargino can lead to a CP violating decay rate asymmetry. We calculate this a…
SUSY-QCD corrections to dark matter annihilations
K. Kovarik, B. Herrmann
We present full QCD and SUSY-QCD corrections to neutralino pair annihilation into quark-antiquark pairs. We show results and numerically evaluate their impact on the neutralino ann…
Two-photon exclusive production of supersymmetric pairs at the LHC
K. Piotrzkowski, N. Schul
The two-photon exclusive production of charged supersymmetric pairs at the LHC has a clean and unique signature - two very forward scattered protons and two opposite charged lepton…
Precise Predictions for Higgs Production in Neutralino Decays
A. C. Fowler
Complete one-loop results, supplemented by two-loop Higgs propagator-type corrections, are obtained for the class of processes chi^0_i->chi^0_j h_a in the MSSM with CP-violating ph…
Phenomenological Consequences of the Constrained Exceptional Supersymmetric Standard Model
P. Athron, S. F. King, D. J. Miller +2
The Exceptional Supersymmetric Standard Model (ESSM) provides a low energy alternative to the MSSM, with an extra gauged U(1) symmetry, solving the -problem of the MSSM.…
AMSB Demystified
Dong-Won Jung, Jae Yong Lee
We reinterpret anomaly-mediated supersymmetry breaking from a field-theoretic perspective in which superconformal anomalies couple to either the chiral compensator or the …
Selecting the Optimal LHC Signatures for Distinguishing Models
Baris Altunkaynak
An algorithm is developed which the goal of producing the most statistically significant signature list for distinguishing between two candidate models given a set of LHC observati…
Phenomenology of a New Supersymmetric Standard Model: The SSM
Carlos Munoz
The SSM solves the problem of the MSSM and explains the origin of neutrino masses by simply using right-handed neutrino superfields. The solution implies the breaking of R-…
Signatures of long-lived colored sparticles
Rasmus Mackeprang
In this paper an updated Geant4 simulation toolkit is presented describing the interactions in matter of heavy hadrons containing long-lived squarks and gluinos. Generic signatures…
Operators in ultraviolet completions for Electroweak collective symmetry breaking
Nobuhiro Uekusa
In a gauge theory with SU(5) broken to SU(2)U(1), the Higgs mass squared receives only logarithmic divergence from all scalar-gauge interactions at one loop. The same patte…
A review on axions and the strong CP problem
Jihn E. Kim
We review the recent developments on axion physics. Some new comments on the strong CP problem, the axion mass, and the simple energy loss mechanism of white dwarfs and related iss…
MFV and the SUSY CP Problem
David M. Straub
The principle of Minimal Flavour Violation (MFV) provides a natural solution to the SUSY flavour problem, but does not solve the SUSY CP problem as it allows for the presence of ne…
The NMSSM implementation in WHIZARD
Juergen Reuter, Felix Braam
The Next-To-Minimal-Supersymmetric extension of the Standard Model (NMSSM) has been in the focus of extensive studies in the past two decades. In anticipation of the LHC era, the i…
NLO electroweak contributions to squark pair production at the LHC
Jan Germer, Wolfgang Hollik, Edoardo Mirabella +1
We present the tree-level and next-to-leading order (NLO) electroweak (EW) contributions to squark-squark production at the Large Hadron Collider (LHC) within the framework of the…
Grand Unified Flavour Physics
Susanne Westhoff
We probe the unification of down quarks and leptons in a supersymmetric SO(10) GUT. The large atmospheric neutrino mixing angle induces bR-sR transitions, which can account for the…
TeV Scale Spontaneous R-Parity Violation
Pavel Fileviez Perez, Sogee Spinner
Understanding the origin or absence of the R-parity violating interactions in the minimal supersymmetric Standard Model is a vital and open issue. Here we show that in the minimal…
Squark pair production at the LHC
U. Langenfeld
We present NNLO cross sections for squark- antisquark production at the LHC. We have calculated new analytic expressions for the scale dependent scaling functions at one and two lo…
