High energy muons in extensive air showers
Carmen Gámez, Miguel Gutiérrez, Juan S. Martínez +1
The production of very high energy muons inside an extensive air shower is observable at telescopes and sensitive to the composition of the primary cosmic ray. Here we discuss…
Little Higgs models with a light T quark
R. Barcelo, M. Masip, M. Moreno-Torres
We study Little Higgs models based on a SU(3)_1 x SU(3)_2 global symmetry and with two scales (the two vacuum expectation values f_{1,2}) substantially different. We show that all…
Quasi-Degenerate Neutrinos and Lepton Flavour Violation in Supersymmetric Models
J. I. Illana, M. Masip
In supersymmetric (SUSY) models the misalignment between fermion and sfermion families introduces unsuppressed flavor-changing processes. Even if the mass parameters are chosen to…
Flavour Changing Neutral Currents in Intersecting Brane Models
S. Abel, M. Masip, J. Santiago
Intersecting D-brane models provide an attractive explanation of family replication in the context of string theory. We show, however, that the localization of fermion families at…
The light Higgs in supersymmetric models with Higgs triplets
M. Masip
In supersymmetric models the presence of Higgs triplets introduce new quartic interactions for the doublets that may raise the mass of the lightest CP-even field up to 205 GeV. We…
1/m_Q corrections in heavy meson decays
M. Masip
We study the form factor f_+^H (H=D,B) involved in H-πtransitions. We use data on D^0 \to π^- l^+ νto find f_+^D at low recoil. Then we use perturbative QCD methods to calculate at…
