Oxidação de lisozima por haloaminas: caracterização química e efeitos biológicos
(Universidade Estadual Paulista (Unesp), 2014-11-07)
As proteínas são macromoléculas complexas de alto peso molecular e que desempenham inúmeras funções nas células. Estas funções podem ser comprometidas caso ocorram modificações nas suas estruturas. Fatores físicos e químicos ...
Dipole moments of the tau-lepton and Z–Z ' mixing angle induced in a 331 model
(IOP Publishing, 2013-01-31)
We obtained bounds on the electromagnetic and weak dipole moments of the tau-lepton in the context of a 331 model. Our bounds on the electromagnetic moments are consistent with the bounds obtained by the L3 and OPAL ...
Probing the electromagnetic dipole moments of the tau-neutrino in the U(1)B−L model at the ILC and CLIC energies
(American Physical Society (APS), 2017-06-19)
In this work we study the sensitivity on the anomalous magnetic and electric dipole moments of the tau
neutrino in the framework of the SU(2)L × U(1)Y × U(1)B−L electroweak model at future e+ e− linear
colliders, such ...
Resonance Chiral Lagrangian analysis of τ -→η(′)π-π0ν τ
(American Physical Society, 2012-10)
The hadronization structure of τ -→ηπ -π0ν τ decays is analyzed using chiral perturbation theory with resonances, considering only the contribution of the lightest meson resonances at leading order in the 1/N C expansion. ...
Search for point-like sources of ultra-high energy neutrinos at the Pierre auger observatory and improved limit on the diffuse flux of tau neutrinos
(Brasil, 2012)
The surface detector array of the Pierre Auger Observatory can detect neutrinos with energy E ν between 1017 eV and 1020 eV from point-like sources across the sky south of +55° and north of –65° declinations. A search has ...
Limits on the electromagnetic and weak dipole moments of the tau-lepton in a 331 model
(Elsevier, 2014)
Using as an input the data obtained by the L3 and OPAL Collaborations for the reaction e+e− → τ+τ−γ at the
Z1-pole, we obtained bounds on the electromagnetic and weak dipole moments of the tau-lepton in the context of a ...
Tau magnetic moment
(Institute of Physics Publishing, 2017)
The τ lepton magnetic moment theoretical predictions and measurements are reviewed. While it is believed that such a high mass particle is a good candidate to show up new physics, this is not the case up to now. The magnetic ...
Bounds on electromagnetic dipole moments of the tau-neutrino in a U(1) B −L model
(IOP Publishing, 2017-08-01)
We study the anomalous magnetic and electric dipole moments of the tau-neutrino
through the process e+ e−.
