Unparticle effects in neutrino telescopes

G. Gonzalez-Sprinberg, R. Martinez, Oscar A. Sampayo

Recently H.Georgi has introduced the concept of unparticles in order to describe the low energy physics of a nontrivial scale invariant sector of an effective theory. We investigat…

The Triple Higgs Boson Self-Coupling at Future Linear e+e- Colliders Energies: ILC and CLIC

A. Gutierrez-Rodriguez, M. A. Hernandez-Ruiz, O. A. Sampayo +2

We analyzed the triple Higgs boson self-coupling at future $e^{+} e^{-}$ colliders energies, with the reactions $e^{+} e^{-} \to b b ˉ H H, t t ˉ H H$ . We evaluate the total cross…

Pairs-Production of Higgs in Association with Bottom Quarks Pairs at $e^{+} e^{-}$ Colliders

A. Gutierrez-Rodriguez, M. A. Hernandez-Ruiz, O. A. Sampayo

In a previous paper, we studied the Higgs pair production in the standard model with the reaction $e^{+} e^{-} \to t t ˉ H H$ . Based on this, we study the Higgs pair production via…

Excited tau lepton contribution to $W - > t a u n u (t a u)$ decay at the one-loop level

Rodolfo A. Diaz, R. Martinez, O. A. Sampayo

We evaluate the compositeness effects of tau lepton on the vertex W-tau-nu(tau) in the context of an effective Lagrangian approach. We consider that only the third family is compos…
