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 ...
Measurement of single charged pion production in the charged-current interactions of neutrinos in a 1.3 GeV wide band beam
(Amer Physical Soc, 2008-08-01)
Single charged pion production in charged-current muon neutrino interactions with carbon is studied using data collected in the K2K long-baseline neutrino experiment. The mean energy of the incident muon neutrinos is 1.3 ...
Measurement of the quasielastic axial vector mass in neutrino interactions on oxygen
(Amer Physical Soc, 2006-09-01)
The weak nucleon axial-vector form factor for quasi-elastic interactions is determined using neutrino interaction data from the K2K Scintillating Fiber detector in the neutrino beam at KEK. More than 12,000 events are ...
Measurement of neutrino oscillation by the K2K experiment
(Amer Physical Soc, 2006-10-01)
We present measurements of ν<sub>μ</sub> disappearance in K2K, the KEK to Kamioka long-baseline neutrino oscillation experiment. One hundred and twelve beam-originated neutrino events are observed in the fiducial volume ...
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 ...
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, ...
Experimental study of the atmospheric neutrino backgrounds for p -> e(+)pi(0) searches in water Cherenkov detectors
(Amer Physical Soc, 2008-02-01)
The atmospheric neutrino background for proton decay via p → e<sup>+</sup>π<sup>0</sup> in ring imaging water Cherenkov detectors is studied with an artificial accelerator neutrino beam for the first time. In total, ...
Quantum gravity, torsion, parity violation, and all that

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 ...
