Update on transversity and Collins functions from SIDIS and e+ e- data

M. Anselmino, M. Boglione, U. D'Alesio +4

We present an update of a previous global analysis of the experimental data on azimuthal asymmetries in semi-inclusive deep inelastic scattering (SIDIS), from the HERMES and COMPAS…

Heavy-quark energy loss and thermalization in a strongly coupled SYM plasma

Guillaume Beuf, Cyrille Marquet, Bo-Wen Xiao

Using the AdS/CFT correspondence, we compute the radiative energy loss of a slowly decelerating heavy quark with mass M moving through a supersymmetric Yang Mills (SYM) plasma at t…

Diffractive cross sections at HERA and diffractive PDFs

Laurent Schoeffel

A large collection of results for the diffractive dissociation of virtual photons, $γ^{⋆} p \to X p$ , have been obtained with the H1 and ZEUS detectors at HERA. Different experim…

Heavy-quark energy loss in pQCD and SYM plasmas

Cyrille Marquet

We consider heavy-quark energy loss and pT-broadening in a strongly-coupled N=4 Super Yang Mills (SYM) plasma, and the problem of finite-extend matter is addressed. When expressed…

The glasma initial state and JIMWLK factorization

F. Gelis, T. Lappi, R. Venugopalan

We review recent work on understanding the next to leading order corrections to the classical fields that dominate the initial stages of a heavy ion collision. We have recently sho…

High energy factorization in nucleus-nucleus collisions III. Long range rapidity correlations

Fermion masses and mixing in models with SO(10) x A_4 symmetry

Federica Bazzocchi, Michele Frigerio, Stefano Morisi

We study the flavour sector in models where the three families of matter are unified in a $(16, 3)$ representation of the $S O (10) \times A_{4}$ group. The necessary ingredients to real…

A light neutralino in hybrid models of supersymmetry breaking

Emilian Dudas, Stephane Lavignac, Jeanne Parmentier

We show that in gauge mediation models where heavy messenger masses are provided by the adjoint Higgs field of an underlying SU(5) theory, a generalized gauge mediation spectrum ar…

Sivers Asymmetries for Inclusive Pion and Kaon Production in Deep-Inelastic Scattering

John Ellis, Dae Sung Hwang, Aram Kotzinian

We calculate the Sivers distribution functions induced by the final-state interaction due to one-gluon exchange in diquark models of nucleon structure, treating the cases of scalar…

Anomalous WW $γ$ coupling in photon-induced processes using forward detectors at the LHC

O. Kepka, C. Royon

We present a new method to test the Standard Model expectations at the LHC using photon-induced $W W$ production. Both $W$ decay in the main ATLAS or CMS detectors while scattered p…

One-Loop Calculations with BlackHat

C. F. Berger, Z. Bern, L. J. Dixon +5

We describe BlackHat, an automated C++ program for calculating one-loop amplitudes, and the techniques used in its construction. These include the unitarity method and on-shell rec…

Perspectives on heavy-quarkonium production at the LHC

J. P. Lansberg, A. Rakotozafindrabe, P. Artoisenet +7

We summarise the perspectives on heavy-quarkonium production at the LHC, both for proton-proton and heavy-ion runs, as emanating from the round table held at the HLPW 2008 Conferen…

A look at the influence of the $J / ψ$ transverse momentum on shadowing

Andry M. Rakotozafindrabe

Stringent physical constraints relate the $J / ψ$ produced at a given transverse momentum $p_{T}$ to the Bjorken- $x$ of the initial gluons. We present a new approach which takes them i…
