  1. 113. Hadronic tau decays in resonance chiral theory
    Prof. Daniel Gomez Dumm (UNLP)

    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...

  2. 119. Direct CP Violation in charmless three-body decays of B mesons

    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...

  3. 148. Charmless three-body B-decays: final state interaction and CP violation
    Prof. Tobias Frederico (Instituto Tecnologico de Aeronautica)
    24/03/2015, 18:00
    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...

  4. 81. Opening angle as an evolution variable for parton distributions
    Prof. Emmanuel de Oliveira (UFSC)
    24/03/2015, 18:30
    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*.

  5. 54. The role of the Unruh effect in multi-particle processes
    Prof. Giorgio Torrieri (JW Goethe Universitat, Frankfurt)
    24/03/2015, 19:00
    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...
