title: "non_resonant_k2V" of "Search for Higgs boson pair production in the $\mathrm{b}\overline{\mathrm{b}}$W$^+$W$^-$ decay mode in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

description: Observed and expected 95% CL upper limits on the nonresonant HH production via VBF cross section as a function of the effective coupling κ2V. The ggF contribution in this case is set to the SM expectation. All other Higgs boson couplings are assumed to have the values predicted by the SM.
description: Results of a search for Higgs boson pair (HH) production with one Higgs boson decaying to two bottom quarks and the other to two W bosons are presented. The search is done using proton-proton collisions data at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 fb$^{−1}$ recorded by the CMS detector at the LHC from 2016 to 2018. The final states considered include at least one leptonically decaying W boson. No evidence for the presence of a signal is observed and corresponding upper limits on the HH production cross section are derived. The limit on the inclusive cross section of the nonresonant HH production, assuming that the distributions of kinematic observables are as expected in the standard model (SM), is observed (expected) to be 14 (18) times the value predicted by the SM, at 95% confidence level. The limits on the cross section are also shown as functions of various Higgs boson coupling modifiers, and anomalous Higgs boson coupling scenarios. In addition, limits are set on the resonant HH production via spin-0 and spin-2 resonances within the mass range 250–900 GeV.

title: "Diff XS v.s. Higgs pt" of "Measurement of the Production Cross Section of a Higgs Boson with Large Transverse Momentum in Its Decays to a Pair of $\tau$ Leptons in Proton-Proton Collisions at $\sqrt{s}$ = 13 TeV"

description: Observed and expected differential fiducial cross sections in bins of Higgs boson $p_{T}$. The last bin include the overflow. The uncertainty bands in the theoretical predictions include uncertainties from the following sources: PDF, renormalization and factorization scales, underlying event and parton showering, and the branching fraction $H\to\tau\tau$.
description: A measurement of the production cross section of a Higgs boson with transverse momentum greater than 250 GeV is presented where the Higgs boson decays to a pair of $\tau$ leptons. It is based on proton-proton collision data collected by the CMS experiment at the CERN LHC at a center-of-mass energy of 13 TeV. The data sample corresponds to an integrated luminosity of 138 fb$^{-1}$. Because of the large transverse momentum of the Higgs boson the $\tau$ leptons from its decays are boosted and produced spatially close, with their decay products overlapping. Therefore, a dedicated algorithm was developed to reconstruct and identify them. The observed (expected) significance of the measured signal with respect to the standard model background-only hypothesis is 3.5 (2.2) standard deviations. The product of the production cross section and branching fraction is measured to be $1.64^{+0.68}_{-0.54}$ times the standard model expectation. The fiducial differential production cross section is also measured as functions of the Higgs boson and leading jet transverse momenta. This measurement extends the probed large-transverse-momentum region beyond 600 GeV.

title: "Table 1" of "Single identified hadron spectra from s(NN)**1/2 = 130-GeV Au + Au collisions."

description: The sources of systematic uncertainties in $\langle p_T \rangle$ and $dN$/$dy$.
description: BNL-RHIC. Transverse momentum spectra and yields of hadrons are measured by the PHENIX collaboration in Au + Au collisions at $\sqrt{s_{NN}}$ = 130 GeV at the Relativistic Heavy Ion Collider (RHIC). The time-of-flight resolution allows identification of pions to transverse momenta of 2 GeV/$c$ and protons and antiprotons to 4 GeV/$c$. The yield of pions rises approximately linearly with the number of nucleons participating in the collision, while the number of kaons, protons, and antiprotons increases more rapidly. The shape of the momentum distribution changes between peripheral and central collisions. Simultaneous analysis of all the $p_T$ spectra indicates radial collective expansion, consistent with predictions of hydrodynamic models. Hydrodynamic analysis of the spectra shows that the expansion velocity increases with collision centrality and collision energy. This expansion boosts the particle momenta, causing the yield from soft processes to exceed that for hard to large transverse momentum, perhaps as large as 3 GeV/$c$.
