#### 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 ...

#### The edge of supersymmetry: Stability walls in heterotic theory

(Elsevier Science Bv, 2009-06-22)

#### Monte Carlo simulation calculation of the critical coupling constant for two-dimensional continuum phi(4) theory

(American Physical Society, 1998-10)

We perform a Monte Carlo simulation calculation of the critical coupling constant for the continuum two-dimensional (lambda/4) phi(4) theory. The critical coupling constant we obtain is [lambda/mu(2)](crit) = 10.26(-.04)(+.08). ...

#### 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 ...

#### Predictions of m(b)/m(tau) and m(t) in an asymptotically nonfree theory

(Amer Physical Soc, 1997-08-01)

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

(American Physical Soc, 2006-03-01)

#### 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 ...

#### 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, ...

#### Quark-lepton unification and lepton flavor nonconservation from a TeV-scale seesaw neutrino mass texture

(American Physical Soc, 2003-10-01)

#### 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 ...
