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. It covers a previously unexplored pseudo-rapidity $$7.2<\eta <8.4$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mrow> <mml:mn>7.2</mml:mn> <mml:mo><</mml:mo> <mml:mi>η</mml:mi> <mml:mn>8.4</mml:mn> </mml:mrow>...
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...
Abstract We measured the surface tension of linear alkylbenzene (LAB) HYBLENE 113 mixed with Diphenyloxazole (PPO) as well pure LAB part material studies for liquid-scintillator based surround background tagger (SBT) in proposed SHiP experiment. The measurement was performed using iron wire method and alkyl benzene plus PPO found to be (30.0 ± 0.6) mN/m 22.0 0.5°C 113, (29.2 at 21.0 0.5°C.
