TL;DR: In this paper, the status of efforts to improve the reinterpretation of searches and measurements at the LHC in terms of models for new physics, in the context of LHC Reinterpretation Forum, is reported.
Abstract: We report on the status of efforts to improve the reinterpretation of searches and measurements at the LHC in terms of models for new physics, in the context of the LHC Reinterpretation Forum. We detail current experimental offerings in direct searches for new particles, measurements, technical implementations and Open Data, and provide a set of recommendations for further improving the presentation of LHC results in order to better enable reinterpretation in the future. We also provide a brief description of existing software reinterpretation frameworks and recent global analyses of new physics that make use of the current data.

TL;DR: In this article, the anomalous magnetic moment of the muon, a lepton flavor violating decay μ→eγ in TeV scale B−L extension of the standard model (SM) with inverse seesaw mechanism was studied.
Abstract: We study the anomalous magnetic moment of the muon, a
μ
, and lepton flavor violating decay μ→eγ in TeV scale B−L extension of the Standard Model (SM) with inverse seesaw mechanism. We show that the B−L contributions to a
μ
are severely constrained; therefore, the SM contribution remains intact. We also emphasize that the current experimental limit of BR(μ→eγ) can be satisfied for a wide range of parameter space and it can be within the reach of MEG experiment.

TL;DR: The anomalous magnetic moment of the muon, a_\mu, and lepton flavor violating decay in TeV scale B-L extension of the standard model with inverse seesaw mechanism was studied in this paper.
Abstract: We study the anomalous magnetic moment of the muon, a_\mu, and lepton flavor violating decay \mu -> e \gamma in TeV scale B-L extension of the Standard Model (SM) with inverse seesaw mechanism. We show that the B-L contributions to a_\mu are severely constrained, therefore the SM contribution remains intact. We also emphasize that the current experimental limit of BR(\mu -> e \gamma) can be satisfied for a wide range of parameter space and it can be within the reach of MEG experiment.

TL;DR: In this paper, the authors show that the addition of a second Higgs doublet, when combined with a dark sector singlet scalar, allows to explain the long-standing anomalies in the Liquid Scintillator Neutrino Detector (LSND) and MiniBooNE (MB) while maintaining compatibility with the null result from KARMEN, and obtain, in the process, a portal to the dark sector, and comfortably account for the observed value of the muon $g\ensuremath{-}2$.
Abstract: We show that one of the simplest extensions of the Standard Model, the addition of a second Higgs doublet, when combined with a dark sector singlet scalar, allows us to $i)$ explain the long-standing anomalies in the Liquid Scintillator Neutrino Detector (LSND) and MiniBooNE (MB) while maintaining compatibility with the null result from KARMEN, $ii)$ obtain, in the process, a portal to the dark sector, and $iii)$ comfortably account for the observed value of the muon $g\ensuremath{-}2$. Three singlet neutrinos allow for an understanding of observed neutrino mass-squared differences via a Type I seesaw, with two of the lighter states participating in the interaction in both LSND and MB. We obtain very good fits to energy and angular distributions in both experiments. We explain features of the solution presented here and discuss the constraints that our model must satisfy. We also mention prospects for future tests of its particle content.

TL;DR: HiggsSignals as discussed by the authors is a program that combines the predictions of models with arbitrary Higgs sectors with the available Higgs signal rate and mass measurements, resulting in a likelihood estimate.
Abstract: The program HiggsSignals confronts the predictions of models with arbitrary Higgs sectors with the available Higgs signal rate and mass measurements, resulting in a likelihood estimate. A new version of the program, HiggsSignals-2, is presented that contains various improvements in its functionality and applicability. In particular, the new features comprise improvements in the theoretical input framework and the handling of possible complexities of beyond-the-SM Higgs sectors, as well as the incorporation of experimental results in the form of simplified template cross section (STXS) measurements. The new functionalities are explained, and a thorough discussion of the possible statistical interpretations of the HiggsSignals results is provided. The performance of HiggsSignals is illustrated for some example analyses. In this context the importance of public information on certain experimental details like efficiencies and uncertainty correlations is pointed out. HiggsSignals is continuously updated to the latest experimental results and can be obtained at https://gitlab.com/higgsbounds/higgssignals.
