Measurement of longitudinal and transverse cross sections in the 3He(e,e′π+)3H reaction at W=1.6 GeV
The coherent 3He(e,e′π+)3H reaction was measured at Q2=0.4 (GeV/c)2 and W=1.6 GeV for two values of the virtual photon polarization, ε, allowing the separation of longitudinal and transverse cross sections. The results ...
False Vacuum at the Heart of Black Holes
It is proposed that the evaporation of black holes via Hawking radiation may conclude at densities and temperatures no higher than those invoked during the inflationary stage of common cosmological models, thus avoiding ...
Magic Matter, the Computational Æther, and the Miner’s Canary
Several viewpoints are proposed with the aim of promoting further approaches to the numerical integration of Einstein's equations, especially its support of attempts to detect astrophysically significant gravitational ...
Measurement of the vector analyzing power in elastic electron-proton scattering as a probe of double photon exchange amplitudes
We report the first measurement of the vector analyzing power in inclusive transversely polarized elastic electron-proton scattering at Q2 = 0.1 (GeV/c)2 and large scattering angles. This quantity should vanish in the ...
Longitudinal Electroproduction of Charged Pions from 1H, 2H, and 3He
(American Physical Society, 2001-11-12)
Separated longitudinal and transverse cross sections for charged pion electroproduction from 1H, 2H, and 3He were measured at Q2 = 0.4(GeV/c)2 for two values of the invariant mass, W = 1.15GeV and W = 1.60GeV, in a search ...
