Large N Approach to Kaon Decays and Mixing 28 Years Later: Delta I = 1/2 Rule, \hat B_K and Delta M_K
Andrzej J. Buras, Jean-Marc Gerard, William A. Bardeen
We review and update our results for K-> pipi decays and K^0-\bar K^0 mixing obtained by us in the 1980s within an approach based on the dual representation of QCD as a theory of w…
Ultimate survival in anomalous psi(2S) decays
J. M. Gerard, A. Martini
The hierarchy among the radiative (, , ) decay channels for the looks quite different from the one. The fate of charm, namely an ultimate…
Weakly-induced strong CP-violation
J. M. Gerard, P. Mertens
Weak interaction contributions to the strong theta parameter are revisited in the frame of a large-Nc Chiral Perturbation Theory. Focusing on the hadronic (eta,etaprime) \to pi pi…
Survival before annihilation in Psi-prime decays
P. Artoisenet, J. -M. Gerard, J. Weyers
We extend the simple scenario for decays suggested a few years ago. The pair in the does not annihilate directly into three gluons but rather survives before an…
The Lemaitre-Schwarzschild Problem Revisited
A. Fuzfa, J. M. Gerard, D. Lambert
The Lemaitre and Schwarzschild analytical solutions for a relativistic spherical body of constant density are linked together through the use of the Weyl quadratic invariant. The c…
Trace anomalies and the rule
J. -M. Gerard, J. Weyers
Trace Anomaly Dominance in weak -decays successfully reproduces the selection rule results, as observed in and $K_L \to π…
Phases and Amplitudes in Inclusive and Decays
J. -M. Gerard, J. Weyers
In inclusive decays of the (3097), electromagnetic and gluonic annihilation amplitudes add incoherently, namely they are 90 out of phase. We argue that this incoherence…
Isospin amplitudes and CP violation in decays
J. -M. Gerard, J. Weyers
We present a simple isospin invariant parametrization for decay amplitudes which consistently includes CP violation and (quasi-elastic) hadronic final states interacti…
A Dynamical Scheme for a Large CP-Violating Phase
D. Delepine, J. -M. Gerard, R. Gonzalez Felipe +1
A dynamical scheme where the third generation of quarks plays a distinctive role is implemented. New interactions with a term induce the breaking of the electroweak symmetry an…
A light stop and electroweak baryogenesis
D. Delepine, J. -M. Gerard, R. Gonzalez Felipe +1
The possibility of creating baryon asymmetry at the electroweak phase transition in the minimal supersymmetric standard model is considered for the case when right-handed squarks a…
Is the standard Higgs scalar elementary?
D. Delepine, J. -M. Gerard, R. Gonzalez Felipe
In the standard electroweak model, the measured top quark mass requires a sizeable Yukawa coupling to the fundamental scalar. This large coupling alone might induce a dynamical bre…
