From factorization to its breaking in diffractive dijet production

M. Klasen

When comparing recent experimental data from the H1 and ZEUS Collaborations at HERA for diffractive dijet production in deep-inelastic scattering (DIS) and photoproduction with nex…

Supersymmetry Parameter Analysis: SPA Convention and Project

J. A. Aguilar-Saavedra, A. Ali, B. C. Allanach +122

High-precision analyses of supersymmetry parameters aim at reconstructing the fundamental supersymmetric theory and its breaking mechanism. A well defined theoretical framework is…

Electromagnetic radiative corrections in parity-violating electron-proton scattering

J. Arvieux, B. Collin, H. Guler +4

QED radiative corrections have been calculated for leptonic and hadronic variables in parity-violating elastic ep scattering. For the first time, the calculation of the asymmetry i…

A chromomagnetic mechanism for the X(3872) resonance

H. Hogaasen, J. M. Richard, P. Sorba

The chromomagnetic interaction, with proper account for flavour-symmetry breaking, is shown to explain the mass and coupling properties of the X(3872) resonance as a = 1$^…

On extrapolations below the Planck scale in models with Lorentz symmetry violation (I)

Luis Gonzalez-Mestres

Most current models of Lorentz symmetry violation (LSV) at the Planck scale involve power-like extrapolations of the Lorentz-beaking term down to accelerator and even much lower en…

The UTfit Collaboration Report on the Status of the Unitarity Triangle beyond the Standard Model I. Model-independent Analysis and Minimal Flavour Violation

UTfit Collaboration, M. Bona, M. Ciuchini +10

Starting from a (new physics independent) tree level determination of rhobar and etabar, we perform the Unitarity Triangle analysis in general extensions of the Standard Model with…
