We discuss the measurement of the charged-current elastic scattering process $e^{-}p\to {\nu }_{e}n$ at the Electron-Ion Collider (EIC). This process provides sensitivity to the poorly constrained axial radius of the nucleon. Collisions of electrons with polarized protons enable measuring the $e^{-}\overrightarrow{p}\to {\nu }_{e}n$ target-spin a…

Most existing and proposed high-energy neutrino experiments have excellent muon charge identification capabilities, enabling the distinction of ${\nu }_{\mu }$ and ${\overline{\nu }}_{\mu }$ charged current interactions.

Flavor hierarchies emerge from a single hierarchical parameter $B$ in a one-flavon Froggatt–Nielsen scheme. Fixing $B=5.357$ from charged-lepton ratios ($m_e:m_{\mu }:m_{\tau }\propto {\epsilon }^5:{\epsilon }^2:1$, $\epsilon =1/B$), we reproduce quark masses and Cabibbo-Kobayashi-Maskawa targets at $M_Z$ with $\mathcal{O}(1)$ coefficients.

It is customary to identify ${\psi }_{+}={\nu }_R+C{\overline{{\nu }_R}}^T$ with a Majorana fermion on the basis of chirality changing charge conjugation $\tilde{C}:{\nu }_R\to C{\overline{{\nu }_R}}^T$ and parity $\tilde{P}:{\nu }_R\to i{\gamma }_4{\nu }_R$. The theorem on the absence of a Majorana-Weyl fermion in $d=4$ states $\tilde{C}{\gamma }_5{\tilde{C}}^{-1}=-{\gamma }_5$ with $\tilde{C}=C{\gamma }_4^T$, and, thus, the charge conjugation of the equivalent…

The Standard Model predicts a long-range force mediated by a pair of neutrinos, known as “the neutrino force.” It scales as $G_F^2/r^5$, where $G_F$ is the Fermi constant. However, as $r\lesssim \sqrt{G_F}$, the four-Fermi theory breaks down and the neutrino force no longer has the $1/r^5$ scaling. For the first time, we derive…
