An influence functional for ultrasoft QCD

F. Guerin, E. Iancu

A real-time path integral for ultrasoft QCD is formulated. It exhibits a Feynman's influence functional. The statistical properties of the theory and the gauge symmetry are explici…

From DIS to proton-nucleus collisions in the Color Glass Condensate model

F. Gelis, J. Jalilian-Marian

We show that particle production in proton-nucleus (pA) collisions in the Color Glass Condensate model can be related to Deep Inelastic Scattering of leptons on protons/nuclei (DIS…

Landau-Pomeranchuk-Migdal resummation for dilepton production

P. Aurenche, F. Gelis, G. D. Moore +1

We consider the thermal emission rate of dileptons from a QCD plasma in the small invariant mass ($Q^2 \sim \gs^2 T^2$) but large energy ($q^0 \gsim T$) range. We derive an integra…

Minimal Scenarios for Leptogenesis and CP Violation

G. C. Branco, R. Gonzalez Felipe, F. R. Joaquim +3

The relation between leptogenesis and CP violation at low energies is analyzed in detail in the framework of the minimal seesaw mechanism. Working, without loss of generality, in a…

Varying Constants in Brane World Scenarios

Ph. Brax, C. van de Bruck, A. -C. Davis +1

Higher-dimensional theories imply that some constants, such as the gravitational constant and the strength of the gauge-couplings, are not fundamental constants. Instead they are r…

Real and Virtual Compton Scattering in a Regge Approach

F. Cano, J. -M. laget

We study Real and Deeply Virtual Compton Scattering in a model based on Regge trajectories and two-gluon exchange. In the kinematic regime of current experiments, the hadronic comp…

Determination of the coupling constant through the process with circularly polarized photons

Michail P. Rekalo, Egle Tomasi-Gustafsson

We suggest a method to determine the product of the coupling constants , in absolute value and relative sign, through the -dependence of the two possible T-even…

Non-Gaussianity in multi-field inflation

Francis Bernardeau, Jean-Philippe Uzan

This article investigates the generation of non-Gaussianity during inflation. In the context of multi-field inflation, we detail a mechanism that can create significant primordial…

Effective Degrees of Freedom at Chiral Restoration and the Vector Manifestation in HLS theory

Masayasu Harada, Youngman Kim, Mannque Rho +1

The question as to what the relevant effective degrees of freedom at the chiral phase transition are remains largely unanswered and must be addressed in confronting both terrestria…

Non linear gluon evolution in path-integral form

J. -P. Blaizot, E. Iancu, H. Weigert

We explore and clarify the connections between two different forms of the renormalisation group equations describing the quantum evolution of hadronic structure functions at small…

Froissart Bound from Gluon Saturation

E. Ferreiro, E. Iancu, K. Itakura +1

We demonstrate that the dipole-hadron cross-section computed from the non-linear evolution equation for the Colour Glass Condensate saturates the Froissart bound in the case of a f…

Higgs boson production via Double Pomeron Exchange at the LHC

M. Boonekamp, A. De Roeck, R. Peschanski +1

We study Higgs boson production via Double Pomeron Exchange allowing for the presence of Pomeron remnants. We estimate the number of events produced at the LHC collider, as a funct…

Intermediate Symmetries in the Spontaneous Breaking of Supersymmetric SO(10)

F. Buccella, C. A. Savoy

We study the supersymmetric spontaneous symmetry breaking of SO(10) into SU(3)xSU(2)xU(1) for the most physically interesting cases of SU(5) or flipped SU(5)xU(1) intermediate symm…

The Colour Glass Condensate: An Introduction

Edmond Iancu, Andrei Leonidov, Larry McLerran

In these lectures, we develop the theory of the Colour Glass Condensate. This is the matter made of gluons in the high density environment characteristic of deep inelastic scatteri…

Associative charm photoproduction with circularly polarized photons

Michail P. Rekalo, Egle Tomasi-Gustafsson

We calculate the asymmetries for the processes and , induced by circularly polarized photons on a…

Conformal invariant saturation

H. Navelet, R. Peschanski

We show that, in onium-onium scattering at (very) high energy, a transition to saturation happens due to quantum fluctuations of QCD dipoles. This transition starts when the order…
