Bayesian Planet Searches for the 10 cm/s Radial Velocity Era

An Integrated Analysis of Radial Velocities in Planet Searches

We discuss a Bayesian approach to the analysis of radial velocities in planet searches. We use a combination of exact and approximate analytic and numerical techniques to efficiently evaluate χ for multiple values of orbital parameters, and to carry out the marginalization integrals for a single planet including the possibility of a long term trend. The result is a robust algorithm that is rapi...

Radial velocity planet detection biases at the stellar rotational period

Future generations of precise radial velocity (RV) surveys aim to achieve sensitivity sufficient to detect Earth mass planets orbiting in their stars’ habitable zones. A major obstacle to this goal is astrophysical RV noise caused by active areas moving across the stellar limb as a star rotates. In this paper, we quantify how stellar activity impacts exoplanet detection with radial velocities a...

Searches for supersymmetry at CMS

Among the most promising prospects for a theory of physics beyond the standard model is supersymmetry. In this talk, the latest results from the CMS experiment at the LHC on searches for supersymmetry produced through through strong production and electroweak production channels are presented using 20/fb of data from the 8 TeV LHC run, with particular focus on gluino and stop searches. Presente...

Searches for Supersymmetry at CMS

CMS has searched for supersymmetry using the full dataset recorded until the end of 2012, at a centerof-mass energy of 8 TeV corresponding to an integrated luminosity of 20 fb-1. The observations are consistent with the expectations from the standard model. CMS maintains a broad spectrum of search strategies that target a wide range of supersymmetric scenarios. A selection of results from very ...
