Low-energy phenomenology of scalar leptoquarks at one-loop accuracy

Valerio Gherardi et al.

Summary: In this study, we conducted a comprehensive examination of the low-energy phenomenology of S-1 and S-3 leptoquarks, focusing on their impact on deviations observed in B-meson decays and the muon magnetic dipole moment. By calculating leptoquark contributions to observables at one-loop accuracy using an effective field theory approach, we presented various scenarios and discussed the preferred parameter space and most relevant observables in each case.

Composite Dark Matter and a horizontal symmetry

Alexandre Carvunis et al.

Summary: In this study, a model of composite Dark Matter is proposed, involving a new QCD-like confining hypercolor sector, hyperbaryons, and weakly coupled gauge bosons H. These elements interact in a way that intriguingly aligns with the mass scale needed to explain rare B-decay discrepancies.

Collider signatures of coannihilating dark matter in light of the B-physics anomalies

Michael J. Baker et al.

Summary: Studied a dark sector with Majorana dark matter and coloured coannihilation partner connected to the Standard Model via a U-1 vector leptoquark; TeV scale U-1 leptoquark is the only successful single-mediator description of B-physics anomalies, showing resonant signatures and excluded by searches at LHC.

Simplified fast detector simulation in MADANALYSIS 5

Jack Y. Araz et al.

Summary: A new simplified fast detector simulator has been introduced in the MadAnalysis 5 platform. By comparing predictions with Delphes 3 software, the results generally agree to a level of about 10% or better, with the largest differences stemming from different strategies used to model specific detector effects. MadAnalysis 5 now offers a user-friendly way to include detector effects when analyzing collider events.

Testing leptoquark/EFT in (B)over-bar → D(*)l(v)over-bar at the LHC

Syuhei Iguro et al.

Summary: The study investigates LHC constraints on New Physics using leptoquark models and an effective-field-theory Hamiltonian. It shows differences between LQs and EFT in terms of applicable LHC bounds. The EFT description is found to be invalid for searching for LQs with mass less than or equal to 10 TeV at the LHC and may lead to overestimated bounds. Future prospects for high luminosity LHC searches include exploring charge asymmetry in background and signal events.

Muon g-2 and B Anomalies from Dark Matter

Giorgio Arcadi et al.

Summary: In light of recent experimental results, a set of models with minimal field content were studied for the first time, addressing dark matter, B anomalies, and the muon g-2 discrepancy. These models, utilizing heavy particles and chiral enhancement, can evade current direct search limits and be tested at present and future colliders.

Contact interactions and top-philic scalar dark matter

Alan S. Cornell et al.

Summary: The study reveals that the presence of contact interactions can significantly affect the dark matter relic density and detection prospects, while leaving the collider phenomenology of the model unaffected. This emphasizes the complementarity of collider and cosmological constraints on dark matter models.

Improving third-generation leptoquark searches with combined signals and boosted top quarks

Arvind Bhaskar et al.

Summary: The search strategies for third-generation leptoquarks involve investigating TeV-scale scalar and vector LQs that decay to top quarks and tau leptons, with a focus on boosted tops and high-p(T) tau leptons for detection. By considering pair and single production processes, the prospects of discovering these LQs at the high luminosity LHC are improved, with optimized selection criteria enhancing the signal detection. Additional three-body single production processes are included to enhance the overall signal detection. Interference effects in the single production channel of charge-1/3 scalar LQ are identified, impacting the prospects at the LHC.

Single leptoquark solutions to the B-physics anomalies

Andrei Angelescu et al.

Summary: Through the introduction of a single leptoquark state and combination with the most recent low energy flavor physics constraints, we find that only the vector leptoquark U1 can provide a viable solution to explain B-anomalies and interestingly predicts a lower bound for lepton flavor violating b -> s mu(+/-)tau(+/-) decay modes.

Leptoquarks and real singlets: A richer scalar sector behind the origin of dark matter

Francesco D'Eramo et al.

Summary: The study focuses on scenarios with scalar leptoquarks acting as portals between the Standard Model and dark matter, investigating the coupling between dark matter, leptoquarks, and the Higgs boson. The potential Yukawa couplings of the leptoquark to quarks and leptons are considered in addressing anomalies in B meson decays, with a particular emphasis on the interplay between astrophysical, collider, and flavor physics bounds on such models. In the heavy dark matter window, the leptoquark portal emerges as the dominant mechanism to explain dark matter abundance, decoupled from the dark matter phenomenology.
