Clustering of B Decay Kinematic Distributions — •Kilian Lieret1, 3, Thomas Kuhr1, 3, and Jason Aebischer2, 3 — 1Ludwig-Maximilians-Universität München — 2Technische Universität München — 3Excellence Cluster Universe
The phenomenology of New Physics models typically depends on a number of free parameters, sometimes strongly influencing the shape of kinematic distributions. Besides being an obvious challenge when presenting exclusion limits on such models, this also is an issue for analyses that need to make assumptions on kinematic distributions in order to extract features of interest, but still want to publish their results in a very general way.
By clustering the New Physics parameter space based on a metric that quantifies the similarity of the resulting kinematic distributions, a small number of New Physics benchmark points can be chosen in such a way that they can together represent the whole parameter space. Experiments can then report exclusion limits and measurements for these benchmark points without sacrificing generality.
In this talk, such a clustering procedure is carried out with kinematic distributions relevant to semileptonic B decays, in particular in light of the recent flavor anomalies.
