Towards a realistic Standard Model from D-brane configurations

Effective low energy models arising in the context of D-brane configurations with Standard Model (SM) gauge symmetry extended by several gauged abelian factors are discussed. The models are classified according to their hypercharge embeddings consistent with the SM spectrum hypercharge assignment. Particular cases are analyzed according to their perspectives and viability as low energy effective field theory candidates. The resulting string scale is determined by means of a two-loop renormalization group calculation. Their implications in Yukawa couplings, neutrinos and flavor changing processes are also presented.

Supersymmetry Breaking Threshold Corrections in the $SU(4)\times SU(2)_L\times SU(2)_R$ Model

We evaluate the SUSY and top threshold effects in the context of the MSSM and the string derived model based on SU(4)$\times$SU(2)$_L\times$SU(2)$_R$. In both cases we run the two loop RGEs and determine the lower bounds of the supersymmetric particle masses, dictated by the experimentally accepted regions of the values of the low energy parameters.

W + gamma + jet production as a test of the electromagnetic couplings of W at LHC and SSC

The reaction $pp \to W \ +\ γ +\ jet \ +\ X$ is considered at centre-of-mass energies $\sqrt{s} = 16$ and $40\;\tev$, including anomalous three-gauge-boson couplings $κ$ and $λ$. The possibility of obtaining limits on these quantities by comparison with the standard model is investigated. The radiation zero properties of the subprocess matrix elements are studied.
