Chiral behavior of the B(s,d)-Bbar(s,d) mixing amplitude in the Standard Model and beyond
Damir Becirevic, Svjetlana Fajfer, Jernej Kamenik
We compute the chiral logarithmic corrections to the Bd and Bs mixing amplitudes in the Standard Model and beyond. We then investigate the impact of the inclusion of the lowest-lyi…
An estimate of the B-->K*gamma form factor
Damir Becirevic, Vittorio Lubicz, Federico Mescia
We present the results of a lattice QCD calculation of the form factor relevant to B-->K*gamma decay. Our final value, T(0) = 0.24 +/- 0.03(+0.04/-0.01), is obtained in the quenche…
How to preserve symmetries with cut-off regularized integrals?
T. Varin, D. Davesne, M. Oertel +1
We present a prescription to calculate the quadratic and logarithmic divergent parts of several integrals employing a cutoff in a coherent way, i.e. in total agreement with symmetr…
Chiral Dynamics beyond the Standard Model
Jan Stern
The SM Lagrangian without physical scalars is rewritten as the LO of a Low-Energy Effective Theory invariant under a higher non linear symmetry S_{nat} \supset SU(2)_W \times U(1)_…
Towards constraints on the SUSY seesaw from flavour-dependent leptogenesis
S. Antusch, A. M. Teixeira
We systematically investigate constraints on the parameters of the supersymmetric type-I seesaw mechanism from the requirement of successful thermal leptogenesis in the presence of…
Resolving the A_{FB}^b puzzle in an extra dimensional model with an extended gauge structure
Abdelhak Djouadi, Gregory Moreau, Francois Richard
It is notorious that, contrary to all other precision electroweak data, the forward-backward asymmetry for b quarks measured in Z decays at LEP1 is nearly three standard…
The Higgs intense--coupling regime in constrained SUSY models and its astrophysical implications
Abdelhak Djouadi, Yann Mambrini
We analyze the Higgs intense--coupling regime, in which all Higgs particles of the Minimal Supersymmetric Standard Model are light with masses of the same order and the value of $\…
Effective Theory Description of Weak Annihilation in B-> Xu l nu Decays
J. J. Sanz-Cillero
The semileptonic B-> Xu l nu decays allow a pretty clean determination of the CKM matrix element |Vub|. Nevertheless, the presence of weak-annihilation effects near the end-point o…
The K^*_0(800) scalar resonance from Roy-Steiner representations of pi K scattering
S. Descotes-Genon, B. Moussallam
We discuss the existence of the light scalar meson K^*_0(800) (also called kappa) in a rigorous way, by showing the presence of a pole in the pi K --> pi K amplitude on the second…
A comparison between the detection of gamma rays and positrons from neutralino annihilation
Y. Mambrini, C. Munoz, E. Nezri
We study the indirect detection of neutralino dark matter using positrons and gamma rays from its annihilation in the galactic halo. Considering the HESS data as the spectrum const…
Relating the description of gluon production in pA collisions and parton energy loss in AA collisions
Yacine Mehtar-Tani
We calculate the classical gluon field of a fast projectile passing through a dense medium. We show that this allows us to calculate both the initial state gluon production in prot…
A new mechanism of neutrino mass generation in the NMSSM with broken lepton number
Asmaa Abada, Gautam Bhattacharyya, Gregory Moreau
In the Minimal Supersymmetric Standard Model with bilinear R-parity violation, only one neutrino eigenstate acquires a mass at tree level, consequently experimental data on neutrin…
The Unitarity Triangle Fit in the Standard Model and Hadronic Parameters from Lattice QCD: A Reappraisal after the Measurements of Delta m_s and BR(B to tau nu)
UTfit Collaboration, M. Bona, M. Ciuchini +10
The recent measurements of the B_s meson mixing amplitude by CDF and of the leptonic branching fraction BR(B to tau nu) by Belle call for an upgraded analysis of the Unitarity Tria…
Constraints on new physics from the quark mixing unitarity triangle
UTfit Collaboration, M. Bona, M. Ciuchini +10
The status of the Unitarity Triangle beyond the Standard Model including the most recent results on Delta m_s, on dilepton asymmetries and on width differences is presented. Even a…
Deciphering the properties of the medium produced in heavy ion collisions at RHIC by a pQCD analysis of quenched large spectra
Rudolf Baier, Dominique Schiff
We discuss the question of the relevance of perturbative QCD calculations for analyzing the properties of the dense medium produced in heavy ion collisions. Up to now leading order…
Is the QCD ghost dressing function finite at zero momentum ?
Ph. Boucaud, Th. Brüntjen, J. P. Leroy +5
We show that a finite non-vanishing ghost dressing function at zero momentum satisfies the scaling properties of the ghost propagator Schwinger-Dyson equation. This kind of Schwing…
Tests of the naturalness of the coupling constants in ChPT at order p^6
Karol Kampf, Bachir Moussallam
We derive constraints on combinations of O(p^6) chiral coupling constants by matching a recent two-loop calculation of the pi-K scattering amplitude with a set of sum rules. We exa…
Updated Constraints on the Minimal Supergravity Model
Abdelhak Djouadi, Manuel Drees, Jean-Loic Kneur
We provide an up-to-date analysis of the parameter space of the minimal supergravity model (mSUGRA). Novel features include the new central value of the top quark mass, an improved…

Proceedings of the CKM 2005 Workshop (WG5), UC San Diego, 15-18 March 2005.
Exploring B_{d,s}-> KK decays through flavour symmetries and QCD-factorisation
Sebastien Descotes-Genon, Joaquim Matias, Javier Virto
We present a new analysis of B_{d,s}->KK modes within the SM, relating them in a controlled way through SU(3)-flavour symmetry and QCD-improved factorisation. We propose a set of s…
K^L_{mu3} decay: A Stringent Test of Right-Handed Quark Currents
Véronique Bernard, Micaela Oertel, Emilie Passemar +1
Clean tests of a small admixture of right-handed quark currents directly coupled to the standard W are still lacking. We show that such non-standard couplings can be significantly…
Physics potential of the CERN-MEMPHYS neutrino oscillation project
J. E. Campagne, M. Maltoni, M. Mezzetto +1
We consider the physics potential of CERN based neutrino oscillation experiments consisting of a Beta Beam (BB) and a Super Beam (SPL) sending neutrinos to MEMPHYS, a 440 kt water…
