SUMMARY:Mathematical and Theoretical Physics Seminar: "Conformal field th
eories and three point functions"
CREATED:20170815T200000Z
DESCRIPTION:Conformal invariance allows additional unique parity-odd tens
or-structures for three-point functions involving the stress tensor\, T\
, and a conserved U(1) current\, j\, in 2+1 dimensional conformal field
theories that violate parity\, apart from the usual parity even structur
es. Following the conformal collider physics setup of Hofman and Maldace
na\, we put constraints on the parity violating as well as parity preser
ving parameters of a general CFT in d=3. We find that large N Chern-Simo
ns theories coupled to a fundamental fermion/boson saturate the bounds t
hat we have derived. An application of the conformal collider bounds is
observed in the form of sum rules which puts constraints on spectral den
sities of any CFT at finite temperature. We derive spectral sum rules in
the shear channel for conformal field theories at finite temperature in
general $d\\geq 3$ dimensions. We show that the sum rule can be written
in terms the parity even Hofman-Maldacena variables $t_2$\, $t_4$ which
determine the three point function of the stress tensor. We then use co
llider constraints and obtain bounds on the sum rule which are valid in
any CFT.
