The B -> Xs gamma Rate and CP Asymmetry within the Aligned Two-Higgs-Doublet Model

Martin Jung, Antonio Pich, Paula Tuzón

In the two-Higgs-doublet model the alignment of the Yukawa matrices in flavour space guarantees the absence of flavour-changing neutral currents at tree level, while introducing ne…

Nonperturbative gluon and ghost propagators in d=3

Joannis Papavassiliou

We study the nonperturbative gluon and ghost propagators in d=3 Yang-Mills, using the Schwinger-Dyson equations of the pinch technique. The use of the Schwinger mechanism leads to…

Heavy Quark Spin Symmetry and Heavy Baryons: Electroweak Decays

C. Albertus, J. E. Amaro, E. Hernandez +1

Heavy quark spin symmetry is discussed in the context of single and doubly heavy baryons. A special attention is paid to the constraints/simplifications that this symmetry imposes…

Photon spectra from quark generation by WIMPs

J. A. R. Cembranos, A. de la Cruz-Dombriz, A. Dobado +2

In this work we provide the fitting formula valid for the simulated photon spectra from WIMP annihilation into light quark-anti quark (qq-) channels in a wide range of WIMP masses.…

Pion radiative weak decays in nonlocal chiral quark models

D. Gomez Dumm, S. Noguera, N. N. Scoccola

We analyze the radiative pion decay pi+ -> e+ nu_e gamma within nonlocal chiral quark models that include wave function renormalization. In this framework we calculate the vector a…

Neutrino phenomenology and stable dark matter with A4

D. Meloni, S. Morisi, E. Peinado

We present a model based on the A4 non-abelian discrete symmetry leading to a predictive five-parameter neutrino mass matrix and providing a stable dark matter candidate. We found…
