Higgs boson tagging with the Lund jet plane

Understand

We construct a procedure to separate boosted Higgs bosons decaying into hadrons, from the background due to strong interactions.

• We employ the Lund jet plane to obtain a theoretically well-motivated representation of the jets of interest and we use the resulting images as the input to a convolutional neural network classifier.
• In particular, we consider two different decay modes of the Higgs boson, namely into a pair of bottom quarks or into light jets, against the respective backgrounds.
• For each case, we consider both a moderate- and high- boost scenario.
