Constraints on two-Higgs-doublet models at large tan beta from W and Z decays
(American Physical Society, 2000-09-01)
We study constraints on type-II two-Higgs-doublet models at large tan beta from CERN LEP and SLD Z-pole data and from lepton universality violation in W decay. We perform a global fit and find that, in the context of Z ...
Transient pulses from exploding primordial black holes as a signature of an extra dimension
(Iop Publishing Ltd, 2008-11-01)
Short distance versus long distance physics: The classical limit of the minimal length uncertainty relation
(American Physical Society, 2002-07-15)
We continue our investigation of the phenomenological implications of the "deformed" commutation relations [(x) over cap (i),(p) over cap (j)]=i (h) over bar[(1+beta(p) over cap (2))delta(ij)+beta'(p) over cap (i)(p) over ...
Quantum gravity, torsion, parity violation, and all that
(American Physical Society, 2005-11)
We discuss the issue of parity violation in quantum gravity. In particular, we study the coupling of fermionic degrees of freedom in the presence of torsion and the physical meaning of the Immirzi parameter from the viewpoint ...
NuTeV anomaly, lepton universality, and nonuniversal neutrino-gauge couplings

Measurement of the quasielastic axial vector mass in neutrino interactions on oxygen

α-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 ...
Search for charged current coherent pion production on carbon in a few-GeV neutrino beam
(Amer Physical Soc, 2008-12-01)
The SciBooNE Collaboration has performed a search for charged current coherent pion production from muon neutrinos scattering on carbon, νυ <sup>12</sup>C &8594; μ <sup>12</sup>Cπ ⁺, with two ...
