\title{Charge eigen state by Dmytro Iakubovskyi}

\begin{document}

\maketitle

 \cref{Charge eigen states} are particle states that couple directly to $W$ and $Z$ gauge bosons of the \cref{Standard Model}. They are what is created directly in weak processes.

For \cref{neutrinos}, the fact that \cref{charge eigen states} do not coincide with \cref{mass eigen states} leads to \cref{neutrino flavor oscillations}. The same effect for strongly-interacting particles is responsible for oscillations of \cref{K-mesons} and \cref{B-mesons}.
