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,...
Abstract SND@LHC is a compact and stand-alone experiment designed to perform measurements with neutrinos produced at the LHC in pseudo-rapidity region of 7.2 < η 8.4. The located 480 m downstream ATLAS interaction point, TI18 tunnel. detector composed hybrid system based on an 830 kg target made tungsten plates, interleaved emulsion electronic trackers, also acting as electromagnetic calorimeter, followed by hadronic calorimeter muon identification system. able distinguish interactions...
We report the direct observation of muon neutrino interactions with SND@LHC detector at Large Hadron Collider. A dataset proton-proton collisions sqrt[s]=13.6 TeV collected by in 2022 is used, corresponding to an integrated luminosity 36.8 fb^{-1}. The search based on information from active electronic components detector, which covers pseudorapidity region 7.2<η<8.4, inaccessible other experiments collider. Muon candidates are identified through their charged-current interaction topology, a...
Abstract The Scattering and Neutrino Detector at the LHC (SND@LHC) started taking data beginning of Run 3 LHC. experiment is designed to perform measurements with neutrinos produced in proton-proton collisions an energy range between 100 GeV 1 TeV.

The SHiP experiment is designed to search for very weakly interacting particles beyond the Standard Model which are produced in a 400 GeV/c proton beam dump at CERN SPS. An essential task keep background level less than 0.1 event after 2× 1020 protons on target. In dump, around 1011 muons will be per second. muon rate spectrometer has reduced by least four orders of magnitude avoid muon-induced combinatorial background. A novel active shield used magnetically deflect out acceptance...
Abstract The SHiP experiment has been proposed at CERN to shed light on phenomena still unexplained in the framework of Standard Model, such as nature dark matter, baryonic asymmetry Universe and neutrino oscillations, searching for hints New Physics. A section detector will be dedicated study physics with special emphasis tau properties, very poorly measured. system identify muons produced interactions, based RPC technology, it is presented detail this paper.
This paper describes DIRAC, the LHCb Monte Carlo production system. DIRAC has a client/server architecture based on: Compute elements distributed among collaborating institutes; Databases for management, bookkeeping (the metadata catalogue) and software configuration; Monitoring cataloguing services updating accessing databases. Locally installed agents implemented in Python monitor local batch queue, interrogate database any outstanding requests using XML-RPC protocol initiate job...

The Beam Gas Vertex (BGV) detector is foreseen as a possible non-invasive beam size measurement instrument for the LHC and its luminosity upgrade. This technique based on reconstruction of beam-gas interaction vertices, where charged particles produced in inelastic interactions are measured with high-precision tracking detectors. design studies expected performance currently developed BGV prototype will be presented an overview given associated vacuum, readout systems. A brief description...
After rapid approval and installation, the SND@LHC Collaboration was able to gather data successfully in 2022 2023. Neutrino interactions from νμs originating at LHC IP1 were observed. Since muons constitute major background for neutrino interactions, muon flux entering acceptance also measured. To improve rejection power of detector increase fiducial volume, a third Veto plane recently installed. The energy resolution calorimeter system measured test beam. This will help with identification...
Abstract The proposed upgrade of the SND@LHC experiment for High Luminosity phase LHC (HL-LHC) will strongly benefit from presence a magnetized region, allowing muon momentum and charge measurement. In this paper we describe an iron core magnet system that is partly integrated with calorimeter designed to respect strict constraints available space in experimental cavern, power consumption, field requirements. Semi-analytical tools are introduced explore parameter space, order define primary...
Today's computing elements for software based high level trigger processing (HLT) are on nodes with multiple cores. Using process parallelization to filter particle collisions from the LHCb experiment such leads expensive consumption of memory and hence significant cost increase. In following an approach is presented both minimize resource applications reduce startup time.
