Nondeterministic approach to tree-based jet substructure.
Jet substructure is typically studied using clustering algorithms, such as k(T), which arrange the jets' constituents into trees. Instead of considering a single tree per jet, we propose that multiple trees should be considered, weighted by an appropriate metric. Then each jet in each event produces a distribution for an observable, rather than a single value. Advantages of this approach includ...
متن کاملPrecision jet substructure from boosted event shapes.
Jet substructure has emerged as a critical tool for LHC searches, but studies so far have relied heavily on shower Monte Carlo simulations, which formally approximate QCD at the leading-log level. We demonstrate that systematic higher-order QCD computations of jet substructure can be carried out by boosting global event shapes by a large momentum Q and accounting for effects due to finite jet s...
متن کاملLight Higgs Searches at the Lhc Using Jet Substructure
One of the major goals of the LHC is to discover the Higgs boson, which is the only particle of the Standard Model (SM) that has not been seen yet at colliders. Even if we cannot predict its mass, SM precision electroweak fits seem to favour a low-mass Higgs,2 and LEP data excluded a mass below 114 GeV.3 That’s why we are going to focus on the search for a light Higgs boson at the LHC, assuming...
متن کاملMining significant substructure-substructure pairs in structural associations
Biological and chemical objects in bioinformatics are often linked to structures: proteins and DNAs to their sequences, small-molecule compounds to their chemical structures, and pathways to their network structures. Associations among these objects, such as interactions between proteins and compounds, are of particular interest in the field, and these associations are often given as a graph: t...
متن کاملKähler Cone Substructure
To define a consistent perturbative geometric heterotic compactification the bundle is required to satisfy a subtle constraint known as “stability,” which depends upon the Kähler form. This dependence upon the Kähler form is highly nontrivial – the Kähler cone splits into subcones, with a distinct moduli space of bundles in each subcone – and has long been overlooked by physicists. In this arti...
