Mapping the SMEFT to discoverable models
Journal of High Energy Physics, 2022 The matching of specific new physics scenarios onto the SMEFT framework is a well-understood procedure. The inverse problem, the matching of the SMEFT to UV scenarios, is more difficult and requires the development of new methods to perform a systematic ...

The role of vector boson fusion in the production of heavy vector triplets at the LHC and HL-LHC
Journal of High Energy Physics, 2022 We clarify the role of vector boson fusion (VBF) in the production of heavy vector triplets at the LHC and the HL-LHC. We point out that the presence of VBF production leads to an unavoidable rate of Drell-Yan (DY) production and highlight the subtle ...

dE/dx from boosted long-lived particles
Journal of High Energy Physics, 2022 At colliders massive long-lived charged particles could be revealed through their anomalously large ionisation energy loss dE/dx. In this paper we explore a class of scenarios in which the LLPs are particularly boosted, owing to production from the decay

Asymmetric leptoquark pair production at LHC
Journal of High Energy Physics, 2023 We investigate asymmetric leptoquark pair production mechanism at the Large Hadron Collider to advocate its potential relevance to establish reliable constraints on the leptoquark parameter space and its ability to aid in correct identification of these ...

One-loop matching of scotogenic model onto standard model effective field theory up to dimension 7
Journal of High Energy Physics, 2022 The scotogenic neutrino seesaw model is a minimal extension of the standard model with three ℤ 2-odd right-handed singlet fermions N and one ℤ 2-odd Higgs doublet η that can accommodate the tiny neutrino mass and provide a dark matter candidate in a ...

Simulation-based anomaly detection for multileptons at the LHC
Journal of High Energy Physics, 2023 Decays of Higgs boson-like particles into multileptons is a well-motivated process for investigating physics beyond the Standard Model (SM). A unique feature of this final state is the precision with which the SM is known.

Simplified models for resonant neutral scalar production with missing transverse energy final states
Journal of High Energy Physics, 2022 Additional Higgs bosons appear in many extensions of the Standard Model (SM). While most existing searches for additional Higgs bosons concentrate on final states consisting of SM particles, final states containing beyond the SM (BSM) particles play an ...

Radiative neutrino masses and the Cohen-Kaplan-Nelson bound
Journal of High Energy Physics, 2023 Recently, an increasing interest in UV/IR mixing phenomena has drawn attention to the range of validity of standard quantum field theory. Here we explore the consequences of such a limited range of validity in the context of radiative models for neutrino

Journal of High Energy Physics, 2022 In a simple extension of the standard model (SM), a pair of vector like lepton doublets (L 1 and L 2) and a SU(2) L scalar doublet (η) have been introduced to help in accommodating the discrepancy in determination of the anomalous magnetic moments of the

Uncovering doubly charged scalars with dominant three-body decays using machine learning
Journal of High Energy Physics, 2023 We propose a deep learning-based search strategy for pair production of doubly charged scalars undergoing three-body decays to W + t b ¯ $$ {W}^{+}t\overline{b} $$ in the same-sign lepton plus multi-jet final state. This process is motivated by composite
