Does anyone know what the smallest particle known is called?

At the moment, all fundamental particles (leptons, quarks, etc)
are believed to be pointlike - i.e. they have no dimension. Their
effective "size" is therefore determined by their wave equations
and so depends on the exact situation.

SPP's... Smallest Physical Particle's
[Mays, 1998]


The separation of which sets the local
variance in the Quantum State that we
detect the effect of as gravitational variance,
also detected is the variance of c through
a locally dense medium. The dense medium
being local higher order groupings of SPP's
forming quarks and all variations of matter.

All SPP's present with a EM signature propagated
wave which due to heterodyne and destructive
/ constructive mixing form stable supersets
of particles which display a EM signature
of the total local SPP groupings...

String Theory describes the EM wave at some
distance from the SPP and models as a fluctuating
energy strings. Because of mathematical
perspective there appears in string theory the
aspect of multiple dimensions which are only
the EM wave of a single SPP viewed as a slice
and each differing angle of the slice produces the
illusion of a string at new dimension. The
seemingly undulating nature such models produce
are the interplay of the EM wave with locally
associated SPP's as EM wave interact...

or maybe not....

Lepton. All leptons are point particles.

Do you mean size, mass, or de Broglie wavelength when you say
"smallest?" Naked or clothed in Feynman diagrams?

Any elementary particle is thought to be point-like, but strengths of
interactions between particles are given as cross-sections, which have
units of area. Neutrinos have the smallest interaction cross-sections.

Depends on your dictionary, *genius*...
