Relating the cosmological constant and supersymmetry breaking in warped compactifications of IIB string theory
(American Physical Society, 2003-02-15)
It has been suggested that the observed value of the cosmological constant is related to the supersymmetry breaking scale M-susy through the formula Lambdasimilar toM(p)(4)(M-susy/M-p)(8). We point out that a similar ...
Effect of the minimal length uncertainty relation on the density of states and the cosmological constant problem
(American Physical Society, 2002-06-15)
We investigate the effect of the minimal length uncertainty relation, motivated by perturbative string theory, on the density of states in momentum space. The relation is implemented through the modified commutation relation ...
Constraints on R-parity violating couplings from CERN LEP and SLAG SLD hadronic observables
(American Physical Society, 2000-07-01)
We analyze the one loop corrections to hadronic Z decays in an R-parity violating extension to the minimal supersymmetric standard model. Performing a global fit to all the hadronic observables at the Z peak, we obtain ...
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 ...
Delta isobar masses, large N-c relations, and the quark model
(American Physical Society, 1999-01-01)
Motivated by recent remarks on the Delta(+) mass and comparisons between the quark model and relations based on large-iri, with perturbative flavor breaking, two sets of Delta masses consistent with these constraints are ...
Background independent quantum mechanics and gravity
(American Physical Society, 2003-09-15)
We argue that the demand of background independence in a quantum theory of gravity calls for an extension of standard geometric quantum mechanics. We discuss a possible kinematical and dynamical generalization of the latter ...
First test of Lorentz violation with a reactor-based antineutrino experiment
(American Physical Society, 2012-12-28)
We present a search for Lorentz violation with 8249 candidate electron antineutrino events taken by the Double Chooz experiment in 227.9 live days of running. This analysis, featuring a search for a sidereal time dependence ...
Direct measurement of backgrounds using reactor-off data in Double Chooz
(American Physical Society, 2013-01-08)
Double Chooz is unique among modern reactor-based neutrino experiments studying (nu) over bar (e) disappearance in that data can be collected with all reactors off. In this paper, we present data from 7.53 days of reactor-off ...
A method for measuring coherent elastic neutrino-nucleus scattering at a far off-axis high-energy neutrino beam target
(American Physical Society, 2014-04-03)
We present a new experimental method for measuring the process of Coherent Elastic Neutrino Nucleus Scattering (CENNS). This method uses a detector situated transverse to a high energy neutrino beam production target. This ...
