Ghost-gluon running coupling, power corrections and the determination of
Ph. Boucaud, F. De Soto, J. P. Leroy +4
We compute a formula including OPE power corrections to describe the running of a QCD coupling non-perturbatively defined through the ghost and gluon dressing functions. This turns…
Hard Pomeron-Odderon interference effects in the production of pi^+pi^- pairs in high energy gamma-gamma collisions at the LHC
B. Pire, L. Szymanowski, F. Schwennsen +1
We estimate the production of two meson pairs in high energy photon photon collisions produced in ultraperipheral collisions at LHC. We show that the study of charge asymmetries ma…
The Higgs sector of supersymmetric theories and the implications for high-energy colliders
Abdelhak Djouadi
One of the main motivations for low energy supersymmetric theories is their ability to address the hierarchy and naturalness problems in the Higgs sector of the Standard Model. In…
Proceedings of SuperB Workshop VI: New Physics at the Super Flavor Factory
D. G. Hitlin, C. H. Cheng, D. M. Asner +46
The sixth SuperB Workshop was convened in response to questions posed by the INFN Review Committee, evaluating the SuperB project at the request of INFN. The working groups address…
Higher Dimensional Operators in the MSSM
I. Antoniadis, E. Dudas, D. M. Ghilencea +1
The origin and the implications of higher dimensional effective operators in 4-dimensional theories are discussed in non-supersymmetric and supersymmetric cases. Particular attenti…
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…
Large gauge invariant non-standard neutrino interactions
M. B. Gavela, D. Hernandez, T. Ota +1
Theories beyond the Standard Model must necessarily respect its gauge symmetry. This implies strict constraints on the possible models of non-standard neutrino interactions, which…
Precise alpha_s from Tau Decays
Bogdan Malaescu
An updated measurement of alpha_s(m_tau) from ALEPH tau hadronic spectral functions is presented. We report a study of the perturbative prediction(s) showing that the fixed-order p…
The precision electroweak data in warped extra-dimension models
Charles Bouchart, Grégory Moreau
The Randall-Sundrum scenario with Standard Model fields in the bulk and a custodial symmetry is considered. We determine the several minimal quark representations allowing to addre…
Integral equation for gauge invariant quark Green's function
H. Sazdjian
We consider gauge invariant quark two-point Green's functions in which the gluonic phase factor follows a skew-polygonal line. Using a particular representation for the quark propa…
On the matrix elements of dB=0 operators in the heavy meson decay widths
Damir Becirevic, Svjetlana Fajfer, Jernej F. Kamenik
We determine the chiral corrections to the matrix elements of the Delta B=0 four-quark operators which are relevant to the studies of the ratios of lifetimes of heavy-light mesons…
Determining the WIMP mass using the complementarity between direct and indirect searches and the ILC
N. Bernal, A. Goudelis, Y. Mambrini +1
We study the possibility of identifying dark matter properties from XENON-like 100 kg experiments and the GLAST satellite mission. We show that whereas direct detection experiments…
Parametrisations of the D -> K l nu form factor and the determination of \hat{g}
Sébastien Descotes-Genon, Alain Le Yaouanc
The vector form factor f_+(t) of the semileptonic decay D -> K l nu, measured recently with a high accuracy, can be used to determine the strong coupling constant g_{D_s^* D K}. Th…
On the IR behaviour of the Landau-gauge ghost propagator
Ph. Boucaud, J. P. Leroy, A. Le Yaouanc +3
We examine analytically the ghost propagator Dyson-Schwinger Equation (DSE) in the deep IR regime and prove that a finite ghost dressing function at vanishing momentum is an altern…
The constrained next-to-minimal supersymmetric standard model
A. Djouadi, U. Ellwanger, A. M. Teixeira
We consider the fully constrained version of the next-to-minimal supersymmetric extension of the standard model (cNMSSM) in which a singlet Higgs superfield is added to the two dou…
The Determination of alpha_s from Tau Decays Revisited
M. Davier, S. Descotes-Genon, A. Hocker +2
We revisit the determination of alpha_s(m_tau) using a fit to inclusive tau hadronic spectral moments in light of (1) the recent calculation of the fourth-order perturbative coeffi…
First Evidence of New Physics in b <--> s Transitions
The UTfit Collaboration, M. Bona, M. Ciuchini +10
We combine all the available experimental information on Bs mixing, including the very recent tagged analyses of Bs to J/Psi phi by the CDF and D0 collaborations. We find that the…
and decays in the fermion triplet seesaw model
A. Abada, C. Biggio, F. Bonnet +2
In the framework of the seesaw models with triplets of fermions, we evaluate the decay rates of and transitions. We show that although, due to neutrino mass c…
Tau energy losses at ultra-high energy: continuous versus stochastic treatment
Oscar Blanch Bigas, Olivier Deligny, Kevin Payet +1
We study the energy losses of the tau lepton in matter through electromagnetic processes at ultra-high energy (UHE). We use both a stochastic and a continuous framework to treat th…
Benchmark scenarios for the NMSSM
A. Djouadi, M. Drees, U. Ellwanger +9
We discuss constrained and semi--constrained versions of the next--to--minimal supersymmetric extension of the Standard Model (NMSSM) in which a singlet Higgs superfield is added t…
B, D and K decays
G. Buchalla, T. K. Komatsubara, F. Muheim +124
With the advent of the LHC, we will be able to probe New Physics (NP) up to energy scales almost one order of magnitude larger than it has been possible with present accelerator fa…
IR finiteness of the ghost dressing function from numerical resolution of the ghost SD equation
Ph. Boucaud, J-P. Leroy, A. Le Yaouanc +3
We solve numerically the Schwinger-Dyson (SD hereafter) ghost equation in the Landau gauge for a given gluon propagator finite at k=0 (alpha_gluon=1) and with the usual assumption…
Light-cone sum rules for form factors revisited
G. Duplancic, A. Khodjamirian, Th. Mannel +2
We reconsider and update the QCD light-cone sum rules for form factors. The gluon radiative corrections to the twist-2 and twist-3 terms in the correlation functions are c…
