several indications for neutral scalars are observed at the lhc. one of them, a broad resonance peaked at about 650 gev which we call h(650), was first observed by an outsider combining published histograms from atlas and cms on zz -> 4 leptons searches, and this combination shows a local significance close to 4 s.d... | h(650) -> w+w-/zz predicts h++ -> w+w+ and h+ -> zw+, as indicated by lhc data |
in order to better understand the emc effect, we propose a clean and precise measurement of the flavor dependence of the emc effect using parity-violating deep inelastic scattering on a 48ca target. this measurement will provide an extremely sensitive test for flavor dependence in the modification of nuclear parton dis... | pvemc: isolating the flavor-dependent emc effect using parity-violating inelastic scattering in solid |
the japan proton accelerator research complex (j-parc) is a hadron-accelerator facility that aims to provide secondary beams of kaons, pions, neutrinos, muons, and others together with the primary proton beam for investigating a wide range of science projects. high-energy hadron physics can be studied by using high-mom... | j-parc hadron physics and future possibilities on color transparency |
a sample of two-proton and no-pion events selected in the argoneut neutrino scattering experiment on a liquid argon target [phys. rev. d 90, 012008 (2014), 10.1103/physrevd.90.012008] is analyzed with the nuwro monte carlo event generator. an attempt is made to estimate how likely it is to obtain observed numbers of la... | search for nucleon-nucleon correlations in neutrino-argon scattering |
observations of suspected coherent elastic neutrino-nucleus scatterings by dark matter direct detection experiments highlight the need for an investigation into the so-called "neutrino floor." we focus on the discovery limit, a statistical concept to identify the neutrino floor, and analyze the asymptotic behavior of t... | asymptotic analysis of binned likelihoods and the neutrino floor |
we consider the resonant production and detection of charged mesons in existing and near-future neutrino scattering experiments with eν≲1 tev , characteristic of high-energy atmospheric neutrinos or collider-sourced neutrino beams. the most promising candidate is the reaction ν¯ee-→ρ-→π-π0. we discuss detection prospec... | resonances in ν¯e-e- scattering below a tev |
