title: "Table Aux. Figure 24 2016 Low-mass" of "Searches for additional Higgs bosons and for vector leptoquarks in $\tau\tau$ final states in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

description: Observed and expected distributions of the variable chosen for statistical inference in the low-mass analysis $m_{\tau\tau}$. Numerical values provided in this table correspond to Figure 24 of the auxilliary material of the publication, but restricted to 2016 data-taking year. All distributions are considered after a fit to data is performed using a background-only model, which includes the $\text{H}(125)$ boson. Some details on how the distributions should be used:


1) All given uncertainties correspond to systematic variations of $\pm1\sigma$.
 2) Upper values ('plus' in the yaml file) correspond to an upward systematic variation of the parameter ($+1\sigma$).
 3) Lower values ('minus' in the yaml file) correspond to a downward systematic variation of the parameter ($-1\sigma$).
 4) These variations can have both positive and negative values, depending on the modelled effect.
 5) Uncertainties with the same name should be treated as correlated, consistently across the upper and lower variations.
 6) Systematic uncertainties with 'prop_' in the name treat limited background statistics per histogram bin, and are deployed with 'Barlow-Beeston-lite' approach. Details in https://arxiv.org/abs/1103.0354 section 5
 7) Remaining systematic uncertainties alter the normalization, the shape, or both for a distribution. The nuisance parameter for such an uncertainty is mapped separately on the normalization and the shape variation components of the uncertainty. For normalization, $\ln$ mapping is used, for shape a spline. Details in https://cms-analysis.github.io/HiggsAnalysis-CombinedLimit/part2/settinguptheanalysis/#binned-shape-analysis
 8) All nuisance parameters for the systematic uncertainties are modelled with a Gaussian pdf.
 9) Gluon fusion contributions are all scaled to 1 pb. Please combine them using either the scale factors from 'Table SM Gluon Fusion Fractions', or using your own composition.
description: Three searches are presented for signatures of physics beyond the standard model (SM) in $\tau\tau$ final states in proton-proton collisions at the LHC, using a data sample collected with the CMS detector at $\sqrt{s} = 13\text{ TeV}$, corresponding to an integrated luminosity of $138\text{ fb}^{-1}$. Upper limits at $95\%$ confidence level ($\text{CL}$) are set on the products of the branching fraction for the decay into $\tau$ leptons and the cross sections for the production of a new boson $\phi$, in addition to the $\text{H}(125)$ boson, via gluon fusion ($gg\phi$) or in association with b quarks, ranging from $\mathcal{O}(10\text{ pb})$ for a mass of $60\text{ GeV}$ to $0.3\text{ fb}$ for a mass of $3.5\text{ TeV}$ each. The data reveal two excesses for $gg\phi$ production with local $p$-values equivalent to about three standard deviations at $m_\phi = 0.1$ and $1.2\text{ TeV}$. In a search for $t$-channel exchange of a vector leptoquark $\text{U}_{1}$, $95\%\text{ CL}$ upper limits are set on the dimensionless $\text{U}_{1}$ coupling to quarks and $\tau$ leptons ranging from $1$ for a mass of $1\text{ TeV}$ to $6$ for a mass of $5\text{ TeV}$, depending on the scenario. In the interpretation of the $M_{h}^{125}$ and $M_{h,\,\text{EFT}}^{125}$ minimal supersymmetric SM benchmark scenarios, additional Higgs bosons with masses below $350\text{ GeV}$ are excluded at $95\%\text{ CL}$.
