Resumen en español Este trabajo analiza potenciales variables que afectan a la corriente de neutro cuando los receptores conectados presentan características no lineales. Se simularon en el programa Alternative Transients Program distintos escenarios combinando el tipo y número de unidades de cargas, alimentadas sucesivamente con tensiones sinusoidales, simétricas, balanceadas, asimétricas y desbalanceadas. También ha sido estudiado el efecto de armónicos en la tensión de alimentaci� (mas) �n. A los efectos de contrastar resultados se registraron mediciones de campo en un centro de cómputos. Como producto de las simulaciones con fuentes asimétricas y desbalanceadas se comprobó variaciones en la corriente de neutro de hasta un 5%. Los análisis de los efectos diversidad y atenuación registraron variaciones más importantes: 10% y 20% respectivamente. Los resultados muestran que las asimetrías y desbalances en las fuentes de alimentación tienen una ligera incidencia en la corriente de neutro, mientras que los efectos diversidad y atenuación fueron más importantes Resumen en inglés This work analyzes potentials variables that affect neutral currents when the receptors connected present nonlinear characteristics. Different scenarios were simulated in the Alternative Transients Program combining the type and number of load units, successively fed with sinusoidal, symmetric, balanced, asymmetric and unbalanced power supply voltage. The effect of harmonics on source voltage was also studied. Field measurements were registered in a computer center to con (mas) trast results. A variation of up to 5% in the neutral current was registered as product of the simulations with asymmetric and unbalanced sources. The analysis of the diversity effect showed variations of a little more than 10% whereas the attenuation effect caused a 20% reduction. The results show that the asymmetries and unbalances in the feeding sources have a slight incidence on neutral currents, whereas the diversity and attenuation effects are more important

Vector-like fermion and standard Higgs production at hadron colliders

Aguila Giménez, Francisco del; Ametller, Lluis; Kane, Gordon L.; Vidal, Jorge

Vector-like fermions are characterized by large neutral current decay rates, in particular into Higgs bosons. If they exist, their clear signals at hadron colliders open a window to Higgs detection, especially to the intermediate Higgs mass region. We discuss in some detail rates and signatures for ...

String goniometry by neutral currents

Aguila Giménez, Francisco del; González, J. A.; Quirós, Mariano

If a new neutral gauge boson exists at accelerator energies, the measurement of the mixing angle(s) fixing its current could to a large extent determine the (heterotic) string model at the Planck scale. In this paper we present the renormalization group predictions for this angle. | Work partially s...

Parity violation correlations in light muonic atoms

Bordes, J.; Vidal, Jorge; Bernabéu, José

The 2 S -1 S transition in light muonic atoms is very sensitive to parity violation correlations induced via neutral currents. Observables depending on these transitions such as the photon polarization and the angular correlation between the emitted radiation and the atom polarization are a clear si...
