title: "Figure 12-b" of "Search for Higgs boson pairs decaying to WW*WW*, WW*$\tau\tau$, and $\tau\tau\tau\tau$ in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

description: Observed and expected $95\%$ CL upper limits on the HH production cross section as a function of the effective coupling $c_{2}$ and the top Yukawa coupling modifier $\kappa_{t}$ for the combination of all seven categories. All Higgs boson couplings other than $c_{2}$ and $\kappa_{t}$ are assumed to have the values predicted in the SM. The position of the SM in the ($c_{2}-\kappa_{t}$) plane, as well as the best fit value of $(c_{2},\kappa_{t})=(1.05, 1.74)$ together with contours for the theory cross section are shown as well.
description: The results of a search for Higgs boson pair ($\textrm{HH}$) production in the $\textrm{WW}^{*}\textrm{WW}^{*}$, $\textrm{WW}^{*}\tau\tau$, and $\tau\tau\tau\tau$ decay modes are presented. The search uses $138~\text{fb}^{-1}$ of proton-proton collision data recorded by the CMS experiment at the LHC at a center-of-mass energy of $13~\mathrm{TeV}$ from 2016 to 2018. Analyzed events contain two, three, or four reconstructed leptons, including electrons, muons, and hadronically decaying tau leptons. No evidence for a signal is found in the data. Upper limits are set on the cross section for nonresonant $\textrm{HH}$ production, as well as resonant production in which a new heavy particle decays to a pair of Higgs bosons. For nonresonant production, the observed (expected) upper limit on the cross section at $95\%$ confidence level (CL) is $21.3$ ($19.4$) times the standard model (SM) prediction. The observed (expected) ratio of the trilinear Higgs boson self-coupling to its value in the SM is constrained to be within the interval $-6.9$ to $11.1$ ($-6.9$ to $11.7$) at $95\%$ CL, and limits are set on a variety of new-physics models using an effective field theory approach. The observed (expected) limits on the cross section for resonant $\textrm{HH}$ production range from $0.18$ to $0.90$ ($0.08$ to $1.06$)$~\mathrm{pb}$ at $95\%$ CL for new heavy-particle masses in the range $250$--$1000~\mathrm{GeV}$.

description: Two separate figures and an apple: one brown male with brown hair with one arm stretched in front of him with a long, narrow dark turquoise scarf draped across his buttocks and down to his feet; one red apple in the center; one orangish pink female with orangish pink hair wearing an orangish pink shirt with brown back and undersleeves, kneeling; remainder of the page is blank.

title: "K+L0_dcs01" of "$K^+\Lambda$ and $K^+\Sigma^0$ photoproduction with fine center-of-mass energy resolution"

description: Excitation function at cos(Theta_K+)cm = -0.8
description: A2 Collaboration at MAMI.
Measurements of $\gamma p \to K^+ \Lambda$ and $\gamma p \to K^+ \Sigma^0$
cross-sections have been obtained with the photon tagging facility
and the Crystal Ball calorimeter at MAMI-C. The measurement uses
a novel $K^+$ meson identification technique in which the weak decay
products are characterized using the energy and timing
characteristics of the energy deposit in the calorimeter, a method
that has the potential to be applied at many other facilities. The
fine center-of-mass energy (W) resolution and statistical accuracy
of the new data results in a significant impact on partial wave
analyses aiming to better establish the excitation spectrum of the
nucleon. Systematic effects from the modeling of the experimental
trigger in the simulation were typically 4% near threshold for
$K^+ \Lambda$ and reducing with the beam energy. For $K^+ \Sigma^0$,
the uncertainty was 2–3% near threshold and only at very backward
angles. Systematic errors from non-hydrogen components of the target
cell, target cell length and PID efficiency were each less than 1%.
