SND@LHC upgrade for the high-luminosity LHC: physics reach and installation scenarios

Abstract The SND@LHC experiment is currently taking data at the Large Hadron Collider (LHC), exploring the unique forward region at pseudorapidities $$7.2<\\eta <8.4$$ 7.2 < η < 8.4 . Its physics programme covers neutrinos originating from heavy-flavour decays and feebly interacting particles produced in proton–proton collisions. Building upon the successful operation of the present detector, this paper presents the physics reach of the approved SND@LHC upgrade for Run 4 of the LHC, and compares it with an alternative installation scenario. Lowering the detector by approximately 40 cm and shifting it horizontally by about 30 cm, while keeping it off-axis, increases the total neutrino interaction rate by a factor of five. The paper describes the design of the upgraded detector and compares the physics performance in both installation scenarios.

Abstract

Abstract The SND@LHC experiment is currently taking data at the Large Hadron Collider (LHC), exploring the unique forward region at pseudorapidities $$7.2<\eta <8.4$$ 7.2 < η < 8.4 . Its physics programme covers neutrinos originating from heavy-flavour decays and feebly interacting particles produced in proton–proton collisions. Building upon the successful operation of the present detector, this paper presents the physics reach of the approved SND@LHC upgrade for Run 4 of the LHC, and compares it with an alternative installation scenario. Lowering the detector by approximately 40 cm and shifting it horizontally by about 30 cm, while keeping it off-axis, increases the total neutrino interaction rate by a factor of five. The paper describes the design of the upgraded detector and compares the physics performance in both installation scenarios.
