Phenomenological Aspects of Heterotic Effective Models At One Loop
Y. Mambrini
We provide a study of the phenomenology of orbifold compactifications of the heterotic string within the context of supergravity effective theories. Our investigation focuses on th…
Relating Incomplete Data and Incomplete Theory
Pierre Binetruy, G. L. Kane, Brent D. Nelson +3
Assuming string theorists will not soon provide a compelling case for the primary theory underlying particle physics, the field will proceed as it has historically: with data stimu…
Remarks on transient photon production in heavy ion collisions
E. Fraga, F. Gelis, D. Schiff
In this note, we discuss the derivation of a formula that has been used in the literature in order to compute the number of photons emitted by a hot or dense system during a finite…
Modified instanton profile effects from lattice Green functions
Ph. Boucaud, F. De Soto, A. Le Yaouanc +4
We trace here instantons through the analysis of pure Yang-Mills gluon Green functions in the Landau gauge for a window of IR momenta (0.4 GeV GeV). We present lattice…
Direct and Indirect Detection of Dark Matter in Heterotic Orbifold Models
Pierre Binetruy, Yann Mambrini, Emmanuel Nezri
We study the neutralino dark matter phenomenology in the context of effective field theories derived from the weakly--coupled heterotic string. We consider in particular direct det…
Physics of the linear collider
Francois Richard
This presentation intends to illustrate the specific capabilities of an ee sub-TeV collider to provide answers on the basic issues in physics: origin of mass, hierarchy of…
Isolated photon + jet photoproduction as a tool to constrain the gluon distribution in the proton and the photon
M. Fontannaz, G. Heinrich
We analyse how the reaction gamma p -> gamma + jet + X can serve to constrain the gluon distributions. Our results are based on a code of partonic event generator type which includ…
SDECAY: a Fortran code for the decays of the supersymmetric particles in the MSSM
M. Muhlleitner, A. Djouadi, Y. Mambrini
We present the Fortran code SDECAY, which calculates the decay widths and branching ratios of all the supersymmetric particles in the Minimal Supersymmetric Standard Model, includi…
A new analysis of scattering from Roy and Steiner type equations
P. Büttiker, S. Descotes-Genon, B. Moussallam
With the aim of generating new constraints on the OZI suppressed couplings of chiral perturbation theory a set of six equations of the Roy and Steiner type for the - and -wav…
Perturbative Odderon in the Dipole Model
Yuri V. Kovchegov, Lech Szymanowski, Samuel Wallon
We show that, in the framework of Mueller's dipole model, the perturbative QCD odderon is described by the dipole model equivalent of the BFKL equation with a -odd initial condi…
Phenomenological Aspects of Heterotic Orbifold Models at One Loop
Pierre Binetruy, Andreas Birkedal-Hansen, Yann Mambrini +1
We provide a detailed study of the phenomenology of orbifold compactifications of the heterotic string within the context of supergravity effective theories. Our investigation focu…
Updated Estimate of the Muon Magnetic Moment Using Revised Results from e+e- Annihilation
M. Davier, S. Eidelman, A. Hocker +1
A new evaluation of the hadronic vacuum polarization contribution to the muon magnetic moment is presented. We take into account the reanalysis of the low-energy e+e- annihilation…
Lower bounds on the curvature of the Isgur-Wise function
A. Le Yaouanc, L. Oliver, J. -C. Raynal
Using the OPE, we obtain new sum rules in the heavy quark limit of QCD, in addition to those previously formulated. Key elements in their derivation are the consideration of the no…
Leptogenesis with four gauge singlets
Asmaa Abada, Marta Losada
We consider a generic type of leptogenesis model which can successfully produce the correct value of the observed baryon number to entropy ratio. The main feature of this model is…
The Uses of Conformal Symmetry in QCD
V. M. Braun, G. P. Korchemsky, D. Mueller
The Lagrangian of Quantum Chromodynamics is invariant under conformal transformations. Although this symmetry is broken by quantum corrections, it has important consequences for st…
Microscopic Models of Heavy Ion Interactions
A. Capella
An introduction to dynamical microscopic models of hadronic and nuclear interactions is presented. Special emphasis is put in the relation between multiparticle production and tota…
Bound state equation in the Wilson loop approach with minimal surfaces
F. Jugeau, H. Sazdjian
The large-distance dynamics in quarkonium systems is investigated, in the large N limit, through the saturation of Wilson loop averages by minimal surfaces. Using a representation…
Nuclear Structure Functions at Small x from Inelastic Shadowing and Diffraction
N. Armesto, A. Capella, A. B. Kaidalov +2
Nuclear structure functions at small x and small or moderate are studied using the relation with diffraction on nucleons which arises from Gribov's Reggeon Calculus. A reason…
Geometric scaling in exclusive processes
S. Munier, S. Wallon
We show that according to the present understanding of the energy evolution of the observables measured in deep-inelastic scattering, the photon-proton scattering amplitude has to…
Impact of CP phases on neutrinoless double beta decay
Asmaa Abada, Gautam Bhattacharyya
We highlight in a model independent way the dependence of the effective Majorana mass parameter, relevant for neutrinoless double beta decay, on the CP phases of the PMNS matrix, u…
Extraction of the x-dependence of the non-perturbative QCD b-quark fragmentation distribution component
E. Ben-Haim, Ph. Bambade, P. Roudeau +2
Using recent measurements of the b-quark fragmentation distribution obtained in events registered at the Z pole, the non-perturbative QCD component of the di…
Confronting Spectral Functions from e+e- Annihilation and tau Decays: Consequences for the Muon Magnetic Moment
Andreas Hocker
Vacuum polarization integrals involve the vector spectral functions which can be experimentally determined from two sources: (i) e+e- annihilation cross sections and (ii) hadronic…
Testing QCD factorisation and charming penguins in charmless
R. Aleksan, P. -F. Giraud, V. Morénas +2
We try a global fit of the experimental branching ratios and CP-asymmetries of the charmless decays according to QCD factorisation. We find it impossible to reach a satis…
