Title: 
Indications of momentum-dependent asymmetric dark matter in the Sun

Speaker: 
Dr. Pat Scott, Imperial College London

Abstract: 
Broad disagreement persists between helioseismological observables
and predictions of solar models computed with the latest surface abundances.
It turns out that most of these problems can be solved by the presence
of asymmetric dark matter coupling to nucleons as the square of
the momentum q exchanged in the collision. I will show that based
on neutrino fluxes, small frequency separations, surface helium
abundances, sound speed profiles and convective zone depths, there is
more than a 6σ preference for q^2 models over the Standard Solar
Model.
The preferred mass (3 GeV) and reference cross-section (10^−37 cm^2 at
a reference momentum of 40 MeV) are within the region of parameter
space allowed by both direct detection and collider searches, but should
be probed soon.
