Recently there has been rapid increase in the number of full statistical models (or "likelihoods") published by the experiments. Most are based on the HistFactory (pyhf) format and published in HEPData. This allows theorists and others to reproduce and combine measurements with the same gold standard as the internal experimental results. However, these are mainly from SUSY and exotics searches...
The US National Science Foundation has funded a 3-year "Research Coordination Network" called FAIROS-HEP. FAIROS-HEP aims to foster the adoption of practices and cyberinfrastructure to enable reuse and reinterpretation of high energy physics (HEP) datasets. The network has funds to support international workshops and to contribute directly to cyberinfrastructure components such as INSPIRE,...
I will discuss the computation of effective action after integrating out heavy scalars and fermions respectively up to dimension eight. The result is very universal. The generic expressions for the effective operators up to dimension eight are computed for the first time and applicable for any UV model. At this current situation when we are looking more precise calculation beyond dimension...
This article studies the production of multiple Higgs bosons from longitudinal vector boson scattering in the context of effective field theories.
The equivalence theorem is employed for a clearer understanding of the $WW\to n\times h$ dynamics.
In this approximation, the Higgs dynamics is determined at lowest order in the general Higgs Effective Theory (HEFT) by the flare function...
Lagrangian terms of an effective field theory (EFT) are commonly organized as an expansion in terms of the EFT power counting. Field space geometry reorganizes these terms in a more efficient way, allowing the direct generalization of some known results to a resummed tower of operators containing higher-order terms, such as the renormalization group equations at one- and two-loop order, some...
Here, we will propose a github repository for collecting and
displaying the best limits on SMEFT Wilson coefficients. We will
explain the bound submission and automated display process for new
contributors and the minimal coding steps included for that. We will
elaborate on how we keep it open-source and involve minimal (or null)
human maintenance. Also, We will discuss the template in...
In the quest for new physics at the LHC, Effective Field Theory (EFT) provides a robust framework for interpreting data. While classical machine learning is an excellent tool for isolating the effects of individual Wilson Coefficients in experimental data, it is limited in its ability to capture the underlying quantum correlations that these coefficients parametrize. This research proposes the...
The ATLAS Collaboration produced a roadmap detailing the challenges of combining top+X measurements to produce coherent probes of the Standard Model predictions and Effective Field Theory (EFT) interpretations. Different approaches for combinations and EFT parameter extractions are outlined, and prerequisites on the harmonisation of physics objects and phase-space regions are described. A plan...
