Light deflection around a spherical charged black hole to second order. Multivariate Padé approximants

From the Reissner-Nordstrom metric we obtain the higher-order terms for the deflection of light around a massive-charged black hole using the Lindstedt-Poincaré method to solve the equation of motion of a photon around the compact object. The corrections are performed developing the expansion in terms of $ε=\frac{r_{c}}{b}$ and $\fracδ{b}= \frac{Q^{2}}{6 πε_{0}Mc^{2} b}$. Additionally, from the perturbation expansion, we obtain multivariate Padé approximants. We also show how these are a better fit for the numerical data than the original formal Taylor series.

Higgs Phenomenology in the Two Higgs Doublet Model of type II. PhD Thesis

We study the Two Higgs Doublet Model of type II, set limits to the parameter $\tanβ$ as a function of the mass of the charged Higgs $m_{H}$, and find interesting discovery channels in hadron colliders or muon colliders. We also obtain the running coupling constants and discuss Grand Unification. A dissertation submitted to the University of San Francisco-Quito in partial fulfillment of the requirements for the degree of Doctor of Phylosophy.

Higgs production at a muon collider in the Two Higgs Doublet Model of type II

We calculate Higgs production cross sections at a muon collider in the Two Higgs Doublet Model of type II. The most interesting productions channels are mu^- mu^+ --> h^0 Z^0, H^0 Z^0, H^- H^+, A^0 Z^0 and H^{-/+} W^{+/-}. The last channel is compared with the production processes p pbar --> H^{-/+} W^{+/-} X and p p --> H^{-/+} W^{+/-} X at the Tevatron and LHC energies, respectively, for large values of tan(beta).
