Résumé |
Motivated by nuclear experiments where a few neutrons are produced by a local
source, we develop a formalism of "nonrelativistic conformal collider physics." We
define detector operators in the nonrelativistic conformal field theory describing
fermions at unitarity. We reduce the problem of computing the momentum
distribution and correlation between final particles produced by a local source
("point-produced") to the computation of correlation functions involving the
detector operators. The general formalism is applied to the point production of
three unitary fermions, where we find the momentum and angular distribution of
final particles, and point production of a large number of fermions. We discuss a
nonrelativistic version of celestial holography, which maps the asymptotic out-
state to a quantum wave function in the so-called "oscillator frame." Based on
