KK Parity in Warped Extra Dimension

Kaustubh Agashe, Adam Falkowski, Ian Low +1

We construct models with a Kaluza-Klein (KK) parity in a five- dimensional warped geometry, in an attempt to address the little hierarchy problem present in setups with bulk Standa…

Exclusive rho^0 electroproduction on the proton : GPDs or not GPDs ?

M. Guidal, S. Morrow

We discuss the interpretation of the process in terms of, on the one hand, Generalized Parton Distributions and, on the other hand, an effective hadronic model based…

Wilson line correlator in the MV model: relating the glasma to deep inelastic scattering

T. Lappi

In the color glass condensate framework the saturation scale measured in deep inelastic scattering of high energy hadrons and nuclei can be determined from the correlator of Wilson…

Dynamics of Non-renormalizable Electroweak Symmetry Breaking

C. Delaunay, C. Grojean, J. D. Wells

We compute the complete one-loop finite temperature effective potential for electroweak symmetry breaking in the Standard Model with a Higgs potential supplemented by higher dimens…

Leptogenesis in SO(10) models with a left-right symmetric seesaw mechanism

A. Abada, P. Hosteins, F. -X. Josse-Michaux +1

We study leptogenesis in supersymmetric SO(10) models with a left-right symmetric seesaw mechanism, including flavour effects and the contribution of the next-to-lightest right-han…

Charge asymmetry for electron (positron)-proton elastic scattering at large angle

E. A. Kuraev, V. V. Bytev, S. Bakmaev +1

Charge asymmetry in electron (positron) scattering arises from the interference of the Born amplitude and the box-type amplitude corresponding to two virtual photons exchange. It c…

Quark-Gluon Plasma/Black Hole duality from Gauge/Gravity Correspondence

Robi Peschanski

The Quark-Gluon Plasma (QGP) is the QCD phase of matter expected to be formed at small proper-times in the collision of heavy-ions at high energy. Experimental observations seem to…

Threshold scans in diffractive W pair production via QED processes at the LHC

M. Boonekamp, J. Cammin, R. Peschanski +1

We propose a new set of measurements which can be performed at the LHC using roman pot detectors. This new method is based on exploiting excitation curves to measure kinematical pr…

Search for two photon exchange from data

E. Tomasi-Gustafsson, E. A. Kuraev, S. Bakmaev +1

We look for asymmetries in the angular distributions of events from recent data on from BABAR collaboration. From first principles, as the C-invariance o…

Physics at a future Neutrino Factory and super-beam facility

The ISS Physics Working Group

The conclusions of the Physics Working Group of the international scoping study of a future Neutrino Factory and super-beam facility (the ISS) are presented. The ISS was carried by…

Nucleon Form Factors and Hidden Symmetry in Holographic QCD

Deog Ki Hong, Mannque Rho, Ho-Ung Yee +1

The vector dominance of the electromagnetic form factors both for mesons and baryons arises naturally in holographic QCD, where both the number of colors and the 't Hooft coupling…

Radiative and isospin-violating decays of Ds mesons in the hadrogenesis conjecture

M. F. M. Lutz, M. Soyeur

The masses and decays of the scalar D_{s0}^*(2317) and axial-vector D_{s1}^*(2460) charmed strange mesons are calculated consistently in the hadrogenesis conjecture. These mesons d…

The pressure of QED from the two-loop 2PI effective action

Szabolcs Borsanyi, Urko Reinosa

We compute the pressure of hot quantum electrodynamics from the two-loop truncation of the 2PI effective action. Since the 2PI resummation guarantees gauge-fixing independence only…

Detecting Chameleons through Casimir Force Measurements

Philippe Brax, Carsten van de Bruck, Anne-Christine Davis +2

The best laboratory constraints on strongly coupled chameleon fields come not from tests of gravity per se but from precision measurements of the Casimir force. The chameleonic for…

Can Inflation Induce Supersymmetry Breaking in a Metastable Vacuum?

Carlos A. Savoy, Arunansu Sil

We argue that fields responsible for inflation and supersymmetry breaking are connected by gravitational couplings. In view of the recent progress in studying supersymmetry breakin…

Testing Chameleon Theories with Light Propagating through a Magnetic Field

P. Brax, C. van de Bruck, A. C. Davis +2

It was recently argued that the observed PVLAS anomaly can be explained by chameleon field theories in which large deviations from Newton's law can be avoided. Here we present the…

Implications of vacuum stability constraints on the nonminimal supersymmetric standard model with lepton number violation

M. Chemtob, P. N. Pandita

We carry out a detailed analysis of the scalar sector of the nonminimal supersymmetric standard model with lepton number violation, and study the constraints imposed on it by the s…

Recent Developments on Kaon Condensation and Its Astrophysical Implications

Gerald E. Brown, Chang-Hwan Lee, Mannque Rho

We discuss three different ways to arrive at kaon condensation at n_c = 3 n_0 where n_0 is nuclear matter density: (1) Fluctuating around the n=0 vacuum in chiral perturbation theo…

Proton Hexality from an Anomalous Flavor U(1) and Neutrino Masses - Linking to the String Scale

Herbi K. Dreiner, Christoph Luhn, Hitoshi Murayama +1

We devise minimalistic gauged U(1)_X Froggatt-Nielsen models which at low-energy give rise to the recently suggested discrete gauge Z_6 symmetry, proton hexality, thus stabilizing…

Common origin of θ_{13} and Δm^2_{12} in a model of neutrino mass with quaternion symmetry

Michele Frigerio, Ernest Ma

The smallness of the 1-3 lepton mixing angle and of the neutrino mass-squared-difference ratio can be understood as the departure from a common limit…

Cosmology and Astrophysics of Minimal Dark Matter

Marco Cirelli, Alessandro Strumia, Matteo Tamburini

We consider DM that only couples to SM gauge bosons and fills one gauge multiplet, e.g. a fermion 5-plet (which is automatically stable), or a wino-like 3-plet. We revisit the comp…
