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...
Particle physics today faces the challenge of explaining mystery dark matter, origin matter over anti-matter in Universe, neutrino masses, apparent fine-tuning electro-weak scale, and many other aspects fundamental physics. Perhaps most striking frontier to emerge search for answers involves new at mass scales comparable familiar below GeV-scale, or even radically below, down sub-eV scales, with very feeble interaction strength. New theoretical ideas address questions predict such feebly...
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>...
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...
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 introduce a novel approach for the reconstruction of particle properties SHiP detector. The experiment significantly focuses on finding effects dark matter interaction. A characteristic trace such an interaction is electromagnetic shower. Our algorithm aims to reconstruct energy and origin showers using online Target Tracker subdetectors that do not suffer from pile-up. Thus, observation excess events with proper can be signal matter. Two different approaches were applied:...
In this chapter we explore a few examples of physics opportunities using the existing chain accelerators at CERN, including potential upgrades. context LHC ring is also considered as part injector system. The objective to find that constitute sensitive probes New Physics ideally cannot be done elsewhere or can significantly better theCERN accelerator complex. Some these may require more flexible complex with additional functionality than just needed inject protons into FCC-hh right energy,...
In Fig. 3, the energy values plotted along axis must be read as 18200 and 18400 eV instead
We discuss a possible strategy for studies of particular next-to-minimal flavor violation New Physics (NP) scenario at LHC. Our analysis is based on comparison CKM matrix elements, which can be obtained from the processes dominated by diagrams different topology (tree, penguin and box). argue that standard formalism overall unitarity triangle fit not suitable searches chosen NP. also stress importance lattice computations some relevant hadronic inputs.
