Description
Typical analyses of neutrino telescope data for signals of WIMP annihilation in the
Sun assume some particular annihilation final states. Upper limits are drawn on
WIMP-nucleon scattering cross-sections as a function of the WIMP mass, which must
then be interpreted in terms of specific particle theories such as supersymmetry.
This interpretation is often complicated by the question of equilibrium between
capture and annihilation in the Sun, the broad range of annihilation final states in
many models, and the resulting neutrino energy spectrum. I will describe a formalism
for quickly and directly comparing event-level IceCube data with arbitrary
annihilation spectra in detailed model scans, considering not only total event
counts, but also event directions and energy estimators. I will show an application
of this formalism to both model exclusion and parameter estimation in models of
supersymmetry, including preliminary results with 22-string data, and projections for
future constraints with 86-string data.
