Bayesian Non-Parametric Event Reconstruction in Super-Kamiokande

Not scheduled


Dr Richard Calland (IPMU)


The Super-Kamiokande collaboration is developing a new water cherenkov reconstruction package that uses a joint charge-time likelihood to reconstruct events. In the case of multiple rings, an optimization method scales poorly. This talk will detail the construction of the joint likelihood, and the application of a Bayesian technique (reversible jump MCMC) to sample the Posterior probability of N discrete ring hypotheses, from which the most likely configuration of rings may be inferred.
