Precision 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...

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...

Light 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...

Identifying Common Substructure for Incremental Methods

In this paper we solve the problem of identifying a “matching” between two logic circuits or “networks”. A matching is a functions that maps each gate or “node” in the new circuit into one in the old circuit (if a matching does not exist it maps it to null). We present both an exact and a heuristic way to solve the maximal matching problem. The matching problem does not require any input corres...

Analytical Methods

Despite the large relative mass difference between different Ca isotopes, the isotopic variability of Ca in natural materials is relatively small. Consequently, high-precision Ca isotope analyses are required to accurately resolve Ca isotope fractionation prior to data interpretation. This chapter summarises techniques which are successfully used to digest samples and to purify different types ...
