Query: Detection Time Distribution for Dirac Particles   The problem of detection time distribution concerns a quantum particle
surrounded by detectors and consists of computing the probability distribution
of where and when the particle will be detected. While the correct answer can
be obtained in principle by solving the Schrodinger equation of particle and
detectors together, a more practical answer should involve a simple rule
representing the behavior of idealized detectors. We have argued elsewhere
[http://arxiv.org/abs/1601.03715] that the most natural rule for this purpose
is the "absorbing boundary rule," based on the 1-particle Schrodinger equation
with a certain "absorbing" boundary condition, first considered by Werner in
1987, at the ideal detecting surface. Here we develop a relativistic variant of
this rule using the Dirac equation and also a boundary condition. We treat one
or several detectable particles, in flat or curved space-time, with stationary
or moving detectors.
