We present a unique general framework allowing for all simulations relevant for simplified t-channel dark matter models at colliders and for the complementary cosmology calculations. We describe how to match next-to-leading-order QCD fixed-order calculations with parton showers to derive robust bounds and predictions in the context of LHC dark matter searches.
We introduce a new event shape observable -- event isotropy -- that quantifies how close the radiation pattern of a collider event is to a uniform distribution. This observable is based on a normalized version of the energy mover's distance, which is the minimum "work'' needed to rearrange one radiation pattern into another of equal energy. We investigate the utility of event isotropy both...
Information deformation and loss in jet clustering are among the major limitations for precisely measuring hadronic events at future $e^-e^+$ colliders. Because of their dominance in data, the measurements of such events are crucial for advancing the precision frontier of Higgs and electroweak physics in the next decades. We show that this difficulty can be well-addressed by synergizing the...
Significant efforts have been put forward at both ATLAS and CMS experiments in search of Vector-like Quarks (VLQs). The results of these searches are relatable in the context of different VLQ models when they are represented in a general fashion. This talk summarizes challenges associated with such interpretations of singly produced VLQ searches and proposes a generalized, semi-analytical...
The relevant information from LHC collision events can be represented as spatial point data in a suitable phase space. The observation of sharp discontinuities in the observed event number density would hint at the presence of new physics beyond the Standard Model. We apply and further improve upon some known wombling techniques from other fields. In the process we refine some of the known...
The JHU generator framework includes an event generator of anomalous HVV and Hff interactions of the Higgs boson in production and decay and a MELA library for matrix element analysis. This framework allows constraints on dimension-six operators of an effective field theory from a joint analysis of on-shell and off-shell production of the Higgs boson and of triple and quartic gauge boson...
Recently there has been a growing interest in the application of quantum computing in many scientific disciplines, including high energy physics. In this talk, we will look at a novel quantum computing based technique to search for unmodeled deviations from a simulated expectation in high-dimensional collider data.
