Important open questions are still present in fundamental Physics and Cosmology, like the nature of Dark Matter, matter-antimatter asymmetry validity Standard Model particle interactions. Addressing these requires a new generation massive detectors to explore subatomic astrophysical worlds. ICARUS T600 is first large mass (760 tons) example able combine imaging capabilities old famous ``bubble chamber'' with excellent energy measurement huge electronic detectors. now operates at Gran Sasso...
We report an early result from the ICARUS experiment on search for a ν μ →ν e signal due to LSND anomaly. The was performed with T600 detector located at Gran Sasso Laboratory, receiving CNGS neutrinos CERN average energy of about 20 GeV, after flight path ∼730 km. anomaly would manifest as excess events, characterized by fast oscillation averaging approximately $\sin^{2}(1.27\Delta m^{2}_{\mathrm{new}}L/E_{\nu})\approx 1/2$ probability $P_{\nu_{\mu}\rightarrow \nu_{e}} = 1/2...
The CERN-SPS accelerator has been briefly operated in a new, lower intensity neutrino mode with ~10^12 p.o.t. /pulse and beam structure made of four LHC-like extractions, each narrow width 3 ns, separated by 524 ns. This very tightly bunched represents substantial progress respect to the ordinary operation CNGS beam, since it allows accurate time-of-flight measurement neutrinos from CERN LNGS on an event-to-event basis. ICARUS T600 detector collected 7 beam-associated events, consistent...
The nature of b-quark jet hadronisation has been investigated using data taken at the Z peak by DELPHI detector LEP. Two complementary methods are used to reconstruct energy weakly decaying b-hadrons, $E_{\mathrm{B}}^{\mathrm{weak}}$ . average value $x^{\mathrm{weak}}_{\mathrm{B}} = E_{\mathrm{B}}^{\mathrm{weak}}/E_{\mathrm{beam}}$ is measured be 0.699±0.011. resulting $x^{\mathrm{weak}}_{\mathrm{B}}$ distribution then analysed in framework two choices for perturbative contribution (parton...
A bstract During May 2012, the CERN-CNGS neutrino beam has been operated for two weeks a total of ~1.8 × 10 17 p.o.t., with proton made bunches, few ns wide and separated by 100 ns. This structure allows very accurate time flight measurement neutrinos from CERN to LNGS on an event-by-event basis. Both ICARUS-T600 PMT-DAQ CERN-LNGS timing synchronization have substantially improved this campaign, taking advantage additional independent GPS receivers, both at as well deployment “White Rabbit”...
Liquid Argon Time Projection Chamber (LAr TPC) detectors offer charged particle imaging capability with remarkable spatial resolution. Precise event reconstruction procedures are critical in order to fully exploit the potential of this technology. In paper we present a new, general approach 3D for LAr TPC practical application track reconstruction. The efficiency method is evaluated on sample simulated tracks. We also analysis stopping tracks collected during ICARUS T600 detector operation...
We report an updated result from the ICARUS experiment on search for {\nu}{\mu} ->{\nu}e anomalies with CNGS beam, produced at CERN average energy of 20 GeV and travelling 730 km to Gran Sasso Laboratory. The present analysis is based a total sample 1995 events neutrino interactions, which corresponds almost doubled respect previously published result. Four clear {\nu}e have been visually identified over full sample, compared expectation 6.4 +- 0.9 conventional sources. compatible absence...
The ICARUS T600 detector, the largest liquid Argon Time Projection Chamber (LAr-TPC) realized after many years of R&D activities, was installed and successfully operated for 3 at INFN Gran Sasso underground Laboratory. One most important issues need an extremely low residual electronegative impurity content in Argon, order to transport free electrons created by ionizing particles with very small attenuation along drift path. solutions adopted recirculation purification systems have permitted...
A search for pair-produced doubly charged Higgs bosons has been performed using the data collected by DELPHI detector at LEP centre-of-mass energies between 189 and 209 GeV. No excess is observed in with respect to Standard Model background. lower limit mass of 97.3 GeV/c2 95% confidence level set left–right symmetric models any value Yukawa coupling τ leptons.
The OPERA collaboration has claimed evidence of superluminal {\nu}{_\mu} propagation between CERN and the LNGS. Cohen Glashow argued that such neutrinos should lose energy by producing photons e+e- pairs, through Z0 mediated processes analogous to Cherenkov radiation. In terms parameter delta=(v^2_nu-v^2_c)/v^2_c, result implies delta = 5 x 10^-5. For this value \delta a very significant deformation neutrino spectrum an abundant production pairs be observed at We present analysis based on...
Single photons detected by the DELPHI experiment at LEP2 in years 1997–2000 are reanalysed to investigate existence of a single extra dimension modified ADD scenario with slightly warped large dimensions. The data collected centre-of-mass energies between 180 and 209 GeV for an integrated luminosity ∼650 pb−1 agree predictions Standard Model allow limit be set on graviton emission one dimension. obtained fundamental mass scale M D is 1.69 TeV/c 2 95% CL, expected 1.71 2.
Understanding the mechanisms of charge generation and their recombination in rutile TiO2 is key importance design optoelectronic photocatalytic devices. In this study, we investigate impact both extrinsic intrinsic defects on photoluminescence (PL) decay dynamics. The exploitation two-photon fluorescence lifetime imaging microscopy (FLIM) enabled differentiation to be made between originating from dislocations bulk Nb-doped TiO2. It was found that pinned at grain boundaries feature lower...
This proposal describes an experimental search for sterile neutrinos beyond the Standard Model with a new CERN-SPS neutrino beam. The experiment is based on two identical LAr-TPC's followed by magnetized spectrometers, observing electron and muon events at 1600 300 m from proton target. project will exploit ICARUS T600, moved LNGS to CERN "Far" position.
