Strong and electroweak interactions in the standard model
Oral presentation
Tau decays are analyzed within the framework of resonance chiral theory.
This is an extension of chiral perturbation theory in which resonances are
incorporated as dynamical states in the Lagrangian, making use of both
chiral symmetry and large N_C considerations. It is seen that after
imposing asymptotic QCD constraints, a few effective coupling constants
need to be fitted from...

Strong and electroweak interactions in the standard model
Oral presentation
Charmless three-body decays of $B^+$ mesons are an excellent laboratory for direct CP violation (CPV) studies. While in two-body decays one measures a single number - the CP asymmetry in the partial decay rates -, in three-body decays the distribution of CP asymmetries across the two-dimensional phase space brings additional information on the underlying mechanisms.
Recently the LHCb...

Strong and electroweak interactions in the standard model
Oral presentation
We will discuss recent results for the formulation of charged three-body $B$ decays in charmless channels, like $KKK$,
$\pi\pi$, $KK\pi$, and $\pi\pi\pi$, introducing the final state interaction in the decay amplitude with
relation to the CPT constraint, while CP violation is allowed. We consider the s-wave interaction between the mesons, coupling between different decay channels and a...

Strong and electroweak interactions in the standard model
Oral presentation
We consider the opening angle as an evolution variable for parton distributions. This allow us to take into account both DGLAP and BFKL leading logarithms and arrive at a single evolution equation, useful for Monte Carlo simulations. Most current global analysis only take into account DGLAP effects, therefore the use of our evolution equation should be particularly important at small *x*.

Strong and electroweak interactions in the standard model
Oral presentation
We discuss the relevance of the Unruh effect in multiparticle processes.
We review the cases where it is nothing more than an effective description of "conventional" multi-particle processes describeable, in the inertial frame, through standard scattering theory, and discuss cases where this equivalency breaks down.
We suggest that an experimental investigation of this issue, achievable in...
