Measuring the $W$-hair of String Black Holes

We have argued previously that the infinitely many gauge symmetries of string theory provide an infinite set of conserved (gauge) quantum numbers ($W$-hair) which characterise black hole states and maintain quantum coherence. Here we study ways of measuring the $W$-hair of spherically-symmetric four...

description We have argued previously that the infinitely many gauge symmetries of string theory provide an infinite set of conserved (gauge) quantum numbers ($W$-hair) which characterise black hole states and maintain quantum coherence. Here we study ways of measuring the $W$-hair of spherically-symmetric four-dimensional objects with event horizons, treated as effectively two-dimensional string black holes. Measurements can be done either through the s-wave scattering of light particles off the string black-hole background, or through interference experiments of Aharonov-Bohm type. In the first type of measurement, selection rules

In the first type of measurement, selection rulesWe continue our studies of ways of measuring the W-hair of spherically-symmetric four-dimensional objects with event horizons, treated as effectively two-dimensional string black holes. Measurements can be done either through the s-wave scattering of light particles off the string black-hole background, or through interference experiments of Aharonov-Bohm type. In the first type of measurement, selection rules restrict the number of particles emitted by the black hole, while in the second method the wave functions of fundamental strings scattered off the black hole have phases that can be measured in appropriate interference experiments.hep-th/9203012CERN-TH-6413-92ACT-2-92CTP-TAMU-12-92ACT-1992-2CERN-TH-6413-92CTP-TAMU-92-12oai:cds.cern.ch:5635681992-03-05
