We review the kinematics of a neutrino beam in the idealized case where the parent mesons momenta are parallel, but without other approximation. This reveals several interesting features, in particular in the off-axis case, which are hidden…
We have measured the beam-normal single-spin asymmetry $A_n$ in the elastic scattering of 1-3 GeV transversely polarized electrons from $^1$H and for the first time from $^4$He, $^{12}$C, and $^{208}$Pb. For $^1$H, $^4$He and $^{12}$C, the…
