Study Of Higgs Production From H -> Zz -> 4l Channel Using Machine Learning Methods, Daniel Arthur Faia Jr.

Graduate Research Theses & Dissertations

In this thesis I will show how machine learning methods can improve on physics analysis in the H -> ZZ -> 4l channel. In particular we will explore how these methods can be used to classify Vector Boson Fusion (VBF) processes in the presence of more dominant Higgs production processes. The aim is to improve the ability to discriminate VBF Higgs boson production relative to other Higgs boson production modes. Since VBF has two quark jets in the final state, it is useful to discriminate between quark and gluon jets. We compare the effectiveness of quark gluon discrimination with machine …

Towards Dual-Readout Calorimetry For Redtop Experiment, Tilak B. Malla

Graduate Research Theses & Dissertations

By virtue of peculiar properties of the eta (η) Goldstone boson, the study of it’s de-

cays is very important. The rare decays of this meson can provide unique opportunities

to probe several fundamental invariance principles of physics world. The REDTOP experi-

ment aims at searching for Physics Beyond Standard Model (BSM) by studying such decays

at a sensitivity of 10^ (−10) or below, which requires 10^ (12) or more η mesons. The REDTOP

collaboration has designed a detector to produce and reconstruct such a large number of

η mesons, which will make REDTOP a rare decay factory. The detector …
