Title: Search for charged Higgs bosons produced in association with a top quark and decaying via H ±→τν using pp collision data recorded at s = 13   TeV by the ATLAS detector

Abstract

Charged Higgs bosons produced in association with a single top quark and decaying via H ±→τν are searched for with the ATLAS experiment at the LHC, using proton–proton collision data at √s=13 TeV corresponding to an integrated luminosity of 3.2 fb -1. The final state is characterised by the presence of a hadronic τ decay and missing transverse momentum, as well as a hadronically decaying top quark, resulting in the absence of high-transverse-momentum electrons and muons. The data are found to be consistent with the expected background from Standard Model processes. A statistical analysis leads to 95% confidence-level upper limits on the production cross section times branching fraction, σ(pp→[b]tH ±)×BR(H ±→τν) , between 1.9 pb and 15 fb, for charged Higgs boson masses ranging from 200 to 2000 GeV. Finally, the exclusion limits for this search surpass those obtained with the proton–proton collision data recorded at √s=8 TeV

  • We present the first measurements of the differential cross section dσ/dp γ Τ for the production of an isolated photon in association with at least two b-quark jets. The measurements consider photons with rapidities |y γ | < 1.0 and transverse momenta 30 < p γ Τ < 200 GeV. The b-quark jets are required to have p jet Τ > 15 GeVand |γ jet| < 1.5. The ratio of differential production cross sections for γ + 2 b-jets to γ +b-jet as a function of p γ Τ is also presented. The results are based on the proton–antiproton collisionmore » data at √s = 1.96 TeV collected with the D0 detector at the Fermilab Tevatron Collider. As a result, the measured cross sections and their ratios are compared to the next-to-leading order perturbative QCD calculations as well as predictions based on the k Τ-factorization approach and those from the sherpa and pythia Monte Carlo event generators.« less

  • Themore » $$\Upsilon$$(1S), $$\Upsilon$$(2S), and $$\Upsilon$$(3S) production cross sections are measured using a data sample corresponding to an integrated luminosity of 35.8 $$\pm$$ 1.4 inverse picobarns of proton-proton collisions at $$\sqrt{s}$$ = 7 TeV, collected with the CMS detector at the LHC. Upsilon resonances are identified through their decays to dimuons. Integrated over the $$\Upsilon$$ transverse momentum range $$p_{t}^{\Upsilon} \lt$$ 50GeV and rapidity range |$$y^\Upsilon$$| $$\lt$$ 2.4, and assuming unpolarized Upsilon production, the products of the Upsilon production cross sections and dimuon branching fractions are \begin{equation*}\sigma(pp \to \Upsilon(1S) X) . B(\Upsilon(1S) \to \mu^+ \mu^-) = (8.55 \pm 0.05^{+0.56}_{-0.50} \pm 0.34) nb,\end{equation*} \begin{equation*}\sigma(pp \to \Upsilon(2S) X) .

Cross section measurements performed within a restricted muon kinematic range and not corrected for acceptance are also provided. These latter measurements are independent of Upsilon polarization assumptions. results are compared to theoretical predictions and previous measurements.« less
