Data Analysis - Algorithms and Tools

Oral

In this talk we discuss algorithms for the analysis of hadronic final states, with application to 1) Single top $t$-channel production; and 2) Heavy Higgs decaying as H->WW, in the lepton plus jets mode. In either case, nature has arranged for the triple decay rates in kinematic angles of the decay, $\theta$,$\theta^*$, and $\phi^*$ to be a short finite series in orthogonal functions,...

Vertex finding in the presence of high-pile up is an important step for reconstructing events at the LHC. In this study we propose a novel approach based on the model-based clustering paradigm. Using the prior distribution of the number of vertices and the prior distribution of the cluster size, i.e. the number of tracks emerging from a vertex, the posterior distribution of the number of...

LHCb has introduced a novel real-time detector alignment and calibration strategy for LHC Run 2. Data collected at the start of the fill is processed in a few minutes and used to update the alignment, while the calibration constants are evaluated for each run. This procedure will improve the quality of the online alignment. Critically, this new real-time alignment and calibration procedure...

The Liquid Argon Time Projection Chamber (LArTPC) has the potential to provide exceptional level of detail in studies on neutrino interactions - a high prioritory field of Intensity Frontier research. Liquid Argon serves as both the target for neutrino interactions and the sensitive medium of the detector, which measures ionization produced by the reaction products. The LArTPC has...
