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 $\langle \text{mass}^2 \rangle$ average, leaving the $\langle \text{mass} \rangle$ 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
