title: "Spectrum analysis: Theoretical beta decay spectrum of 12B" of "Interpreting Reactor Antineutrino Anomalies with STEREO data"

description: 12B prediction used for the control of the energy scale. The three most intense beta decay branches of 12B have been taken into account, covering 99.94% of the total decay rate. The corresponding spectra are given in bins of 50 keV, normalized to their respective branching ratio. The [no rad. corr] notation stands for the fact that we didn't include the radiative corrections in our nominal simulation, as all radiated photons should be absorbed in the STEREO target volume. However the full effect of these corrections is included in the uncertainty of the predicted spectrum. It can be deduced from the comparison with the full calculation of the beta branches given here as well.

description: The 95% confidence level upper limits on the product of the production cross section and branching fraction of the $Z\phi$ signal with scalar couplings in the $\tau\tau$ decay scenario. The red line is the theoretical prediction for the product of the production cross section and branching fraction of the $Z\phi$ signal.
description: A search for beyond the standard model spin-0 bosons, $\phi$, that decay into pairs of electrons, muons, or tau leptons is presented. The search targets the associated production of such bosons with a $\mathrm{W}$ or $\mathrm{Z}$ gauge boson, or a top quark-antiquark pair, and uses events with three or four charged leptons, including hadronically decaying tau leptons. The proton-proton collision data set used in the analysis was collected at the LHC from 2016 to 2018 at a center-of-mass energy of $13\TeV$, and corresponds to an integrated luminosity of $138\fbinv$. The observations are consistent with the predictions from standard model processes. Upper limits are placed on the product of cross sections and branching fractions of such new particles over the mass range of 15 to $350\GeV$ with scalar, pseudoscalar, or Higgs-boson-like couplings, as well as on the product of coupling parameters and branching fractions. Several model-dependent exclusion limits are also presented. For a Higgs-boson-like $\phi$ model, limits are set on the mixing angle of the Higgs boson with the $\phi$ boson. For the associated production of a $\phi$ boson with a top quark-antiquark pair, limits are set on the coupling to top quarks. Finally, limits are set for the first time on a fermiophilic dilaton-like model with scalar couplings and a fermiophilic axion-like model with pseudoscalar couplings.

title: "Cross section limits for VLL pair production" of "Search for pair-produced vector-like leptons in final states with third-generation leptons and at least three b quark jets in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

description: Expected and observed $95\%$ CL upper limits on the product of the VLL pair production cross section and the branching fraction to third generation quarks and leptons, combining the 2017 and 2018 data and all $\tau_\textrm{h}$ multiplicity channels. The theoretical prediction in the 4321 model for electroweak production of VLLs is also shown.
description: The first search is presented for vector-like leptons (VLLs) in the context of the "4321 model", an ultraviolet-complete model with the potential to explain existing PB physics measurements that are in tension with standard model predictions. The analyzed data, corresponding to an integrated luminosity of $96.5~\textrm{fb}^{-1}$, were recorded in 2017 and 2018 with the CMS detector at the LHC in proton-proton collisions at $\sqrt{s}=13\,\mathrm{TeV}$. Final states with $\geq3$ b-tagged jets and two third-generation leptons ($\tau\tau$, $\tau\nu_{\tau}$, or $\nu_{\tau}\nu_{\tau}$) are considered. Upper limits are derived on the VLL production cross section in the VLL mass range 500-1050 GeV. The maximum likelihood fit prefers the presence of signal at the level of 2.8 standard deviations, for a representative VLL mass point of $600\,\textrm{GeV}$. As a consequence, the observed upper limits are approximately double the expected limits.
