#### Notes on spacetime thermodynamics and the observer dependence of entropy

(American Physical Society, 2004-03)

Because of the Unruh effect, accelerated and inertial observers differ in their description of a given quantum state. The implications of this effect are explored for the entropy assigned by such observers to localized ...

#### NuTeV anomaly, lepton universality, and nonuniversal neutrino-gauge couplings

(American Physical Society, 2004-12)

In previous studies we found that models with flavor-universal suppression of the neutrino-gauge couplings are compatible with NuTeV and Z-pole data. In this paper we expand our analysis to obtain constraints on flavor-dependent ...

#### alpha-states in de Sitter space

(American Physical Society, 2005-02)

Field theory in de Sitter space admits a one-parameter family of vacua determined by a superselection parameter alpha. Of these vacua, the Euclidean vacuum uniquely extrapolates to the vacuum of flat Minkowski space. States ...

#### NuTeV anomaly, neutrino mixing, and a heavy Higgs boson

(American Physical Society, 2003-04)

Recent results from the NuTeV experiment at Fermilab and the deviation of the Z invisible width, measured at CERN LEP and the SLAC Linear Collider, from its standard model (SM) prediction suggest the suppression of neutrino-Z ...

#### Leptonic CP violation search and the ambiguity of delta m(31)(2)

(American Physical Society, 2006-03)

We consider a search for the CP-violating angle delta(CP) in long baseline neutrino oscillation experiments. We show that the subleading delta(CP)-dependent terms in the nu(mu)->nu(e) oscillation probability can be easily ...

#### Thermal production of axions in the Earth

(American Physical Society, 2009-05)

We estimate the production rate of axion-type particles in the core of the Earth, at a temperature T approximate to 5000 K. We constrain thermal geo-axion emission by demanding a core-cooling rate less than O(100) K/Gyr, ...

#### Exact solution of the harmonic oscillator in arbitrary dimensions with minimal length uncertainty relations

(American Physical Society, 2002-06-15)

We determine the energy eigenvalues and eigenfunctions of the harmonic oscillator where the coordinates and momenta are assumed to obey the modified commutation relations [(x) over cap (i),(p) over cap (j)]=i (h) over ...

#### 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 ...
