Quantization of Fayet-Iliopoulos parameters in supergravity
(American Physical Society, 2011-04-08)
In this short article we discuss quantization of the Fayet-Iliopoulos parameter in supergravity theories. We argue that, in supergravity, the Fayet-Iliopoulos parameter determines a lift of the group action to a line bundle, ...
Position and momentum uncertainties of the normal and inverted harmonic oscillators under the minimal length uncertainty relation
(American Physical Society, 2011-11-18)
We analyze the position and momentum uncertainties of the energy eigenstates of the harmonic oscillator in the context of a deformed quantum mechanics, namely, that in which the commutator between the position and momentum ...
Search for massive neutrinos in the decay pi -> e nu
(American Physical Society, 2011-09-06)
Evidence of massive neutrinos in the pi(+) -> e(+)nu decay spectrum was sought with the background pi(+) -> mu(+) -> e(+) decay chain highly suppressed. Upper limits (90% C. L.) on the neutrino mixing matrix element vertical ...
