We present a measurement of the flux neutrino-induced upgoing muons (<Eν>∼ 100 GeV) using MACRO detector. The ratio number observed to expected events integrated over all zenith angles is 0.74 ±0.036 (stat) ±0.046 (systematic) ±0.13 (theoretical). distribution for −1.0≤cosθ≤−0.1 does not fit well with no oscillation expectation, giving maximum probability χ2 0.1%. acceptance detector has been extensively studied downgoing muons, independent analyses and Monte Carlo simulations. other...

The fully contained events detected in the NUSEX nucleon stability experiment have been analysed to search for possible anomalies fluxes of atmospheric neutrinos. measured flux muon neutrinos is very good agreement with predictions and no anomaly has found ratio between rate electron neutrino events.

We have measured the cross section of radiative process e+e- -> pi+pi-gamma with KLOE detector at Frascati phi-factory DAPHNE, from events taken a CM energy W=1 GeV. Initial state radiation allows us to obtain for pi+pi-, pion form factor |F_pi|^2 and dipion contribution muon magnetic moment anomaly, Delta a_mu^{pipi} = (478.5+-2.0_{stat}+-5.0_{syst}+-4.5_{th}) x 10^{-10} in range 0.1 < M_{pipi}^2 0.85 GeV^2, where theoretical error includes SU(3) ChPT estimate uncertainty on photon final...

The existence of a new force beyond the Standard Model is compelling because it could explain several striking astrophysical observations which fail standard interpretations. We searched for light vector mediator this dark force, $\mathrm{U}$ boson, with KLOE detector at DA$\Phi$NE $\mathrm{e}^{+}\mathrm{e}^{-}$ collider. Using an integrated luminosity 1.54 fb$^{-1}$, we studied process $\mathrm{e}^{+}\mathrm{e}^{-} \to \mathrm{U}\gamma$, $\mathrm{U} \mathrm{e}^{+}\mathrm{e}^{-}$, using...

We have searched for a light vector boson U, the possible carrier of "dark force", with KLOE detector at DAΦNE e+e− collider, motivated by astrophysical evidence presence dark matter in Universe. Using collisions collected an integrated luminosity 239.3 pb−1, we look dimuon mass peak reaction e+e−→μ+μ−γ, corresponding to decay U→μ+μ−. find no U signal. set 90% CL upper limit mixing parameter squared between photon and 1.6×10−5 8.6×10−7 region 520<mU<980 MeV.

The recent interest in a light gauge boson the framework of an extra U(1) symmetry motivates searches mass range below 1 GeV. We present search for such particle, dark photon, e+e−→Uγ, U→π+π− based on 28 million e+e−→π+π−γ events collected at DAΦNE by KLOE experiment. π+ π− production initial-state radiation compensates loss sensitivity previous U→e+e−, μ+μ− due to small branching ratios ρ–ω resonance region. found no evidence signal and set limit 90% CL mixing strength between photon ε2, U...

The vertical underground muon intensity has been measured in the slant depth range 3200–7000 hg cm−2 (standard rock) with completed lower part of MACRO detector at Gran Sasso laboratory, using a large sample data. These observations are used to compute surface flux and primary ''all-nucleon'' spectrum.

A bstract The three precision measurements of the cross section σ ( e + − → π γ(γ)) using initial state radiation by KLOE collaboration provide an important input for prediction hadronic contribution to anomalous magnetic moment muon. These are correlated both statistical and systematic uncertainties and, therefore, simultaneous use these requires covariance matrices that fully describe correlations. We present construction them determine a combined measurement γ(γ)). find, from this...
