Viability of strongly coupled scenarios with a light Higgs-like boson.

We present a one-loop calculation of the oblique S and T parameters within strongly coupled models of electroweak symmetry breaking with a light Higgs-like boson. We use a general effective Lagrangian, implementing the chiral symmetry breaking SU(2)(L) [Symbol: see text]SU(2)(R) → SU(2)(L+R) with Goldstone bosons, gauge bosons, the Higgs-like scalar, and one multiplet of vector and axial-vector massive resonance states. Using a dispersive representation and imposing a proper ultraviolet behavior, we obtain S and T at the next-to-leading order in terms of a few resonance parameters.

Two-loop effective theory analysis of pi (K)-->enu[over ]_{e}[gamma] branching ratios.

We study the ratios R_{e/mu};{(P)} identical withGamma(P-->enu[over ]_{e}[gamma])/Gamma(P-->munu[over ]_{mu}[gamma]) (P=pi, K) in Chiral Perturbation Theory to order e;{2}p;{4}. We complement the two-loop effective theory results with a matching calculation of the counterterm, finding R_{e/mu};{(pi)}=(1.2352+/-0.

[Primary septicemias in pediatric patients. Hospital Infantil de la Paz (1990-1993)].

Background: Septicemias comprise more than one third of nosocomial infections in children. Their risk factors are related with the exposition time, therefore they are evaluated in relationship to it.

Patients And Methods: Prospective observational study along 4 years in surgical children and in those entered in the Internal Medicine Unit patients of a children Hospital, with stays higher than two days.

Zuclopenthixol decanoate in schizophrenia: serum levels and clinical state.

Serum concentrations of zuclopenthixol were determined in a group of 20 patients treated with a depot preparation, zuclopenthixol decanoate in Viscoleo. Clinical assessments according to a Clinical Global Impression (CGI) scale, Comprehensive Psychological Rating Scale (CPRS), 16-item subscale for schizophrenia, and the UKU side effect scale were performed on 3 consecutive days of injection. The serum concentrations showed a limited individual variation and a high and significant correlation between dose and serum concentration.
