Search for New Physics with two Higgs bosons and missing transverse momentum at the ATLAS experiment

Supervisor: Dr. Chiara Rizzi, Univ. of Geneva

The Higgs boson, discovered in 2012, completes the Standard Model of Particle Physics but also provides an excellent opportunity to search for new phenomena. In some New Physics models, a pair of Higgs bosons can be produced in association with dark matter particles, which interact only weakly and therefore escape undetected, giving rise to an energy imbalance in the event (missing transverse momentum). We will search for these events focusing on the cases where each Higgs boson decays to a pair of b-quarks.
Depending on the interests of the student, the project can focus on different areas of the analysis, ranging from background estimate techniques to the design of machine learning methods to reconstruct the particles in the events and discriminate between New Physics and Standard Model events.
