We have searched for a deeply bound kaonic state by using the FINUDA spectrometer installed at e+e− collider DAΦNE. Almost monochromatic K−’s produced through decay of ϕ(1020) mesons are used to observe K− absorption reactions stopped on very thin nuclear targets. Taking this unique advantage, we succeeded detect kaon-bound K−pp its two-body into Λ hyperon and proton. The binding energy width determined from invariant-mass distribution as 115+6−5(stat)+3−4(syst) MeV 67+14−11(stat)+2−3(syst)...
A new general purpose fixed target facility is proposed at the CERN SPS accelerator which aimed exploring domain of hidden particles and make measurements with tau neutrinos. Hidden are predicted by a large number models beyond Standard Model. The high intensity 400~GeV beam allows probing wide variety containing light long-lived exotic masses below ${\cal O}$(10)~GeV/c$^2$, including very weakly interacting low-energy SUSY states. experimental programme capable being extended in future,...
A bstract Heavy Neutral Leptons (HNLs) are hypothetical particles predicted by many extensions of the Standard Model. These can, among other things, explain origin neutrino masses, generate observed matter-antimatter asymmetry in Universe and provide a dark matter candidate. The SHiP experiment will be able to search for HNLs produced decays heavy mesons travelling distances ranging between $$ \mathcal{O} <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>O</mml:mi>...

The Search for Hidden Particles (SHiP) Collaboration has shown that the CERN SPS accelerator with its 400 GeV/c proton beam offers a unique opportunity to explore Sector [1–3]. proposed experiment is an intensity frontier which capable of searching hidden particles through both visible decays and scattering signatures from recoil electrons or nuclei. high-intensity experimental facility developed by SHiP based on number key features developments provide possibility probing large part...
We present an analysis of muon events with all multiplicities collected during 21804 h operation the first Large Volume Detector tower. The measured angular distribution intensity has been converted to "depth–vertical-intensity" relation in depth range from 3 12 km w.e. this allowed us derive power index γ primary all-nucleon spectrum: γ=2.78±0.05. standard rock and comparison data other experiments done. also derived vertical spectrum at sea level.Received April...
