Higgs phenomenology in the Stealth Doublet Model

Rikard Enberg, Johan Rathsman, Glenn Wouda

We analyze a model for the Higgs sector with two scalar doublets and a symmetry that is manifest in the Yukawa sector but broken in the potential. Thus, one of the doublets b…

Impact of nucleon matrix element uncertainties on the interpretation of direct and indirect dark matter search results

R. Ruiz de Austri, C. Pérez de los Heros

We study in detail the impact of the current uncertainty in nucleon matrix elements on the sensitivity of direct and indirect experimental techniques for dark matter detection. We…

Dispersive analysis for

C. Hanhart, A. Kupsc, U. -G. Meißner +2

A dispersion integral is derived that connects data on to the transition form factor. A detailed analysis of the uncertainties is provided. We find for t…

Higgs properties in the Stealth Doublet Model

Glenn Wouda

I present a model with two scalar doublets and a softly broken $\ztwo$ symmetry, where only one of the doublets gets a vacuum expectation value and couples to fermions at tree-leve…

Probing the Pomeron structure using dijets and +jet events at the LHC

C. Marquet, C. Royon, M. Saimpert +1

We consider hard diffractive events in proton-proton collisions at the LHC, in which both protons escape the collision intact. In such double Pomeron exchange processes, we propose…

Reactions with pions and vector mesons in the sector of odd intrinsic parity

Carla Terschlüsen, Bruno Strandberg, Stefan Leupold +1

The Wess-Zumino-Witten structure is supplemented by a simple vector-meson Lagrangian where the vector mesons are described by antisymmetric tensor fields. With the ρ-ω-π coupling a…

Higgs properties in a broken Inert Doublet Model

Rikard Enberg, Johan Rathsman, Glenn Wouda

We consider a model for the Higgs sector with two scalar doublets and a broken symmetry, the Stealth Doublet Model, where the symmetry is manifest in the Yukawa sector…

Solar wind test of the de Broglie-Proca's massive photon with Cluster multi-spacecraft data

Alessandro Retino, Alessandro D. A. M. Spallicci, Andris Vaivads

Our understanding of the universe at large and small scales relies largely on electromagnetic observations. As photons are the messengers, fundamental physics has a concern in test…

A QCD description of the ATLAS jet veto measurement

Y. Hatta, C. Marquet, C. Royon +3

We present a new QCD description of the ATLAS jet veto measurement, using the Banfi-Marchesini-Smye equation to constrain the inter-jet QCD radiation. This equation resums emission…
