The NESSiE experiment is designed to perform an accurate measurement of muon-neutrino disappearance at small L/E, in order to severely constrain models with more than three-standard neutrinos, or even determine for the first time the presence of a new kind of neutrino oscillation. NESSiE is a Short-Baseline experiment with magnetic spectrometers at two different sites on the FNAL-Booster neutrino beam. The experiment would allow to definitively solve the existing tension of the muon-neutrino disappearance result with the appearance and disappearance anomalies at eV mass scale, by spanning one more order of magnitude in the mixing angle between standard and sterile neutrinos. We demonstrate that this project constitutes the most robust and fast way to unambigously study the neutrino physics at that scales.
APEX is an experiment at Thomas Jefferson National Accelerator Facility (JLab) in Virginia, USA, that searches for a new gauge boson ($A^prime$) with sub-GeV mass and coupling to ordinary matter of $g^prime sim (10^{-6} - 10^{-2}) e$. Electrons impin
We outline the opportunities for spin physics which are offered by a next generation and multi-purpose fixed-target experiment exploiting the proton LHC beam extracted by a bent crystal. In particular, we focus on the study of single transverse spin asymetries with the polarisation of the target.
We present recent results obtained by the KLOE-2 Collaboration at the DAPHNE e+e- collider. The first class of results concerns search for dark forces at the scale of 1 GeV in associated production of gamma and the U boson, in search for the Higgsstr
We argue that the concept of a multi-purpose fixed-target experiment with the proton or lead-ion LHC beams extracted by a bent crystal would offer a number of ground-breaking precision-physics opportunities. The multi-TeV LHC beams will allow for the
We report on the opportunities for spin physics and Transverse-Momentum Dependent distribution (TMD) studies at a future multi-purpose fixed-target experiment using the proton or lead ion LHC beams extracted by a bent crystal. The LHC multi-TeV beams
