Hadron Production Measurements for Long-Baseline Neutrino Experiments with NA61/SHINE

A precise prediction of the neutrino flux is a key ingredient for achieving the physics goals of long-baseline neutrino experiments. In modern accelerator-based neutrino experiments, neutrino beams are created from the decays of secondary hadrons produced in hadron-nucleus interactions. Hadron production is the leading systematic uncertainty source on the neutrino flux prediction; therefore, its precise measurement is essential. The NA61/SHINE is a fixed-target experiment at the CERN Super Proton Synchrotron, which studies hadron production in hadron-nucleus and nucleus-nucleus collisions for various physics goals. For neutrino physics, light hadron beams (protons, pions, and kaons) are collided with a light nuclear target (carbon, aluminum, and beryllium) and spectra of outgoing hadrons are measured. These proceedings will review the recent results and ongoing hadron production measurements with NA61/SHINE for the precise neutrino flux predictions in the T2K and Fermilab long-baseline neutrino experiments. It will also discuss the prospects for future hadron production measurements with NA61/SHINE beyond 2020, after the Long Shutdown 2 of the accelerator complex at CERN.Comment: Talk presented at CIPANP2018. 8 pages, LaTeX, 8 figures. arXiv admin note: text overlap with arXiv:1705.0053

Hadron Production Experiments

Precise prediction of the neutrino flux is a key ingredient to achieving the physics goals of accelerator-based neutrino experiments. In modern accelerator-based neutrino experiments, neutrino beams are created by colliding protons with a nuclear target. Secondary hadrons are produced in these collisions, and their decays contribute to the neutrino flux. The hadron production is the leading systematic uncertainty source on the neutrino flux prediction; therefore its precise measurement is desirable. In these proceedings, review of recent hadron production measurements and the latest results from the NA61/SPS Heavy Ion and Neutrino Experiment (NA61/SHINE) are presented. In addition, plans of NA61/SHINE hadron production measurements for the next generation neutrino experiments and NA61/SHINE physics program extension beyond 2020 are discussed.Comment: Talk presented at NuPhys2016 (London, 12-14 December 2016). 8 pages, LaTeX, 10 figure

Higgs Search in bbˉb\bar{b} Signatures at ATLAS and CMS

We report on searches for the Standard Model Higgs boson decaying to $b \bar{b}$ in $pp$ collisions at the ATLAS and CMS experiments. These rely on signatures where the Higgs boson is produced in association with a vector boson or in association with a top-quark pair. Results are presented, based on $5.0~\mathrm{fb}^{-1}$ of $pp$ collision data at $\sqrt{s} = 7$~TeV and up to $13.0~\mathrm{fb}^{-1}$ of data at $\sqrt{s} = 8$~TeV collected by the LHC accelerator. These are expressed in terms of 95\% confidence level upper limits on the production cross section of the Standard Model Higgs boson times the branching ratio to decay to $b$-quark pair.Comment: 8 pages. 14th International Conference on B-Physics at Hadron Machines (Beauty 2013), 8-12 April 2013, Bologna, Ital
