A Comparison of the LSND and KARMEN Anti-neutrino Oscillation Experiments
The LSND and KARMEN neutrino oscillation experiments are compared in order to
clarify the significance of the apparent disagreement between their results.Comment: 6 pages, 2 figures. To be in the proceedings of COSMO-9
Quantum Black Hole Wave Packet: Average Area Entropy and Temperature Dependent Width
A quantum Schwarzschild black hole is described, at the mini super spacetime
level, by a non-singular wave packet composed of plane wave eigenstates of the
momentum Dirac-conjugate to the mass operator. The entropy of the mass spectrum
acquires then independent contributions from the average mass and the width.
Hence, Bekenstein's area entropy is formulated using the average, leaving the average to set the
Hawking temperature. The width function peaks at the Planck scale for an
elementary (zero entropy, zero free energy) micro black hole of finite rms
size, and decreases Doppler-like towards the classical limit.Comment: 5 PRD pages, 1 figure; v.2 minor typo correction
