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 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. An analysis systematic uncertainties introduced by interaction models atmosphere propagation muons is presented. A comparison our results published data also presented.Received 3 April...

Using 5.33 × 106 single muons collected in 1.46 104 live hours by MACRO during the period 1991–1994, we have searched for a correlation between variations underground muon rate, Nμ, and seasonal temperature atmosphere. These correlations are found to be present with high statistical significance. Analysis of relatively complete December 1992–December 1994 subset data yields value coefficient, αT = (TNμ)(∂Nμ∂T) 0.83±0.13. total set gives consistent results. We compared this result hypothesis...

We perform an indirect search for Weakly Interacting Massive Particles (WIMPs) using the MACRO detector to look neutrino-induced upward-going muons resulting from annihilation of WIMPs trapped in Sun and Earth. The is conducted various angular cones centered on Earth accommodate a range WIMP masses. No significant excess over background atmospheric neutrinos seen limits are placed muon fluxes These used constrain neutralino particle parameters supersymmetric theory, including those suggested...

High-energy gamma-ray astronomy is now a well-established field, and several sources have been discovered in the region from few giga-electron volts up to tera-electron volts. If involving hadronic processes exist, production of photons would be accompanied by neutrinos too. Other possible neutrino could related annihilation weakly interacting, massive particles (WIMPs) at center galaxies with black holes. We present results search for pointlike using 1100 upward-going muons produced...
