Measurement of higgs boson production in H → W W ∗ → eνμν decays at ATLAS via multivariate analysis

Abstract: Since the theoretical foundation of the electroweak force symmetry breaking and the Higgs boson were first proposed by Peter Higgs, Robert Brout and Francois Englert in 1964, particle physicists have been seeking the experimental verification ever since. The discovery of the Higgs Boson paved the path for further studies in other Higgs decay channels and has allowed for more sophisticated model, for searches beyond the Standard Model physics. The H → W W ∗ → eνμν channel offers a sizable signal and moderate background yields, enabling accurate measurements of gluon fusion (ggF), vector boson fusion (VBF) and Higgs Strahlung (VH) productions of the Higgs boson.
In this thesis, a blinded study on the implementation of neural network classifiers as a replacement for Higgs transverse mass discriminant variable for the zero and one jet categories of the gluon fusion production channel, in the decay to eνμν is sought. Furthermore, an investigation of regression recurrent neural networks is also sought as a competing predictor for the Higgs boson transverse momentum, and as a replacement for the reconstructed momenta via the signature energy deposition
