Combining higher-order resummation with multiple NLO calculations and parton...
AbstractWe extend the lowest-order matching of tree-level matrix elements with parton showers to give a complete description at the next higher perturbative accuracy in αs at both small and large jet...
View ArticleA gauge field theory of continuous-spin particles
AbstractWe propose and quantize a local, covariant gauge-field action that unifies the description of all free helicity and continuous-spin degrees of freedom in a simple manner. This is the first...
View ArticleExotic top partners and Little Higgs
AbstractLittle Higgs models often give rise to top partners beyond the minimal ones necessary for the cancellation of quadratic divergences. We review how this occurs and discuss the phenomenology of...
View ArticleAnomaly mediation in local effective theories
AbstractThe phenomenon known as “anomaly mediation” can be understood in a variety of ways. Rather than an anomaly, certain gaugino bilinear terms are required by local supersymmetry and gauge...
View ArticleJet observables without jet algorithms
AbstractWe introduce a new class of event shapes to characterize the jet-like structure of an event. Like traditional event shapes, our observables are infrared/collinear safe and involve a sum over...
View ArticleJet shapes with the broadening axis
AbstractBroadening is a classic jet observable that probes the transverse momentum structure of jets. Traditionally, broadening has been measured with respect to the thrust axis, which is aligned along...
View ArticleSoft drop
AbstractWe introduce a new jet substructure technique called “soft drop declustering”, which recursively removes soft wide-angle radiation from a jet. The soft drop algorithm depends on two parameters...
View ArticleToward multi-differential cross sections: measuring two angularities on a...
AbstractThe analytic study of differential cross sections in QCD has typically focused on individual observables, such as mass or thrust, to great success. Here, we present a first study of double...
View ArticleJet Vetoes interfering with H → WW
AbstractFar off-shell Higgs production in H→ WW, ZZ, is a particularly powerful probe of Higgs properties, allowing one to disentangle Higgs width and coupling information unavailable in on-shell rate...
View ArticleA hybrid strong/weak coupling approach to jet quenching
AbstractWe propose and explore a new hybrid approach to jet quenching in a strongly coupled medium. The basis of this phenomenological approach is to treat physics processes at different energy scales...
View ArticlePileup per particle identification
AbstractWe propose a new method for pileup mitigation by implementing “pileup per particle identification” (PUPPI). For each particle we first define a local shape α which probes the collinear versus...
View ArticleUsing energy peaks to measure new particle masses
AbstractWe discussed in arXiv:1209.0772 that the laboratory frame distribution of the energy of a massless particle from a two-body decay at a hadron collider has a peak whose location is identical to...
View ArticleGaining (mutual) information about quark/gluon discrimination
AbstractDiscriminating quark jets from gluon jets is an important but challenging problem in jet substructure. In this paper, we use the concept of mutual information to illuminate the physics of...
View ArticlePower counting to better jet observables
AbstractOptimized jet substructure observables for identifying boosted topologies will play an essential role in maximizing the physics reach of the Large Hadron Collider. Ideally, the design of...
View ArticleThe weak scale from BBN
AbstractThe measured values of the weak scale, v, and the first generation masses, mu,d,e, are simultaneously explained in the multiverse, with all these parameters scanning independently. At the same...
View ArticleNon-Higgsable QCD and the standard model spectrum in F-theory
AbstractMany four-dimensional supersymmetric compactifications of F-theory contain gauge groups that cannot be spontaneously broken through geometric deformations. These “non-Higgsable clusters”...
View ArticleJet-images: computer vision inspired techniques for jet tagging
AbstractWe introduce a novel approach to jet tagging and classification through the use of techniques inspired by computer vision. Drawing parallels to the problem of facial recognition in images, we...
View ArticlePrecision Higgsstrahlung as a probe of new physics
AbstractA “Higgs factory”, an electron-positron collider with center-of-mass energy of about 250 GeV, will measure the cross section of the Higgsstrahlung process, e+e−→ hZ, with sub-percent precision....
View ArticleIdentifying boosted new physics with non-isolated leptons
AbstractWe demonstrate the utility of leptons which fail standard isolation criteria in searches for new physics at the LHC. Such leptons can arise in any event containing a highly boosted particle...
View ArticleThe first calculation of fractional jets
AbstractIn collider physics, jet algorithms are a ubiquitous tool for clustering particles into discrete jet objects. Event shapes offer an alternative way to characterize jets, and one can define a...
