Feasibility of τ -lepton electromagnetic dipole moments measurement using bent crystal at the LHC

open access: yesJournal of High Energy Physics, 2019
In this paper we discuss the possibility of measuring the anomalous magnetic and electric dipole moments of the τ lepton. The method consists in studying the spin precession induced by the strong effective magnetic field inside channels of a bent crystal

Sensitivity of the SHiP experiment to light dark matter

open access: yesJournal of High Energy Physics, 2021
Dark matter is a well-established theoretical addition to the Standard Model supported by many observations in modern astrophysics and cosmology. In this context, the existence of weakly interacting massive particles represents an appealing solution to ...

Charm production in fixed target experiments

open access: yesZeitschrift für Physik C Particles and Fields, 1983
Prompt lepton production in proton beam dump experiments has been critically analysed within the general frame work of $$A_c \bar D$$ and $$D\bar D$$ production and ...

Searching for dark sector with missing mass technique in fixed target experiments [PDF]

open access: yesEPJ Web of Conferences, 2019
Currently, the existence of a dark sector almost completely decoupled from the Standard Model is a viable solution for numerous long-standing problems in physics, including the nature of dark matter and the muon anomalous magnetic moment.

A study of the K + → π 0 e + νγ decay

open access: yesJournal of High Energy Physics, 2023
A sample of 1.3 × 105 K + → π 0 e + νγ candidates with less than 1% background was collected by the NA62 experiment at the CERN SPS in 2017–2018. Branching fraction measurements are obtained at percent relative precision in three restricted kinematic ...

LHC fixed target experiments

open access: yes, 2019
Several fixed-target experiments at the LHC are being proposed and actively studied. Splitting of beam halo from the core by means of a bent crystal combined with a second bent crystal after the target has been suggested in order to study magnetic and ...

A high efficiency photon veto for the Light Dark Matter eXperiment

open access: yesJournal of High Energy Physics, 2020
Fixed-target experiments using primary electron beams can be powerful discovery tools for light dark matter in the sub-GeV mass range. The Light Dark Matter eXperiment (LDMX) is designed to measure missing momentum in high-rate electron fixed-target ...

III.14 — CERN beamline for fixed-target experiments [PDF]

open access: yes
Fixed-target experiments are continuing to play a major role in the very beginnings of accelerator-based studies in particle physics. While collider experiments dominate the exploration in the high-energy domain, fixed-target experiments still cover the ...

Improved calorimetric particle identification in NA62 using machine learning techniques

open access: yesJournal of High Energy Physics, 2023
Measurement of the ultra-rare K + → π + ν ν ¯ $$ {K}^{+}\to {\pi}^{+}\nu \overline{\nu} $$ decay at the NA62 experiment at CERN requires high-performance particle identification to distinguish muons from pions.
