The initial iota and upsilon have the diaeresis.
It uses points, breathing, and accents sparingly; iota and upsilon sometimes have diaeresis.
It uses diaeresis over initial upsilon; two corrections were made.
These peaks are associated with subatomic particles (such as nucleons, delta baryons, upsilon mesons) and their excitations.
It is the equivalent of the phi (strange quark, strange antiquark), psi (charm quark, charm antiquark) and upsilon (bottom quark, bottom antiquark) mesons.
