  The Standard Model (SM) is a successful approach to particle physics
calculations. However, there are indications that the SM is only a good
approximation to an underlying non-local reality involving fundamental entities
(preons) that are not point particles. Furthermore, our universe seems to be
dominated by a vacuum energy/cosmological constant. The holographic principle
then indicates only a finite number of bits of information will ever be
available to describe the observable universe, and that requires a holographic
preon model linking the (0,1) holographic bits to SM particles. All SM
particles have charges 0, 1/3, 2/3 or 1 in units of the electron charge, so the
bits in a holographic preon model must be identified with fractional electric
charge. Such holographic charged preon models require baryon asymmetry and also
suggest a mechanism for stationary action. This paper outlines a holographic
charged preon model where preons are strands with finite energy density
specified by bits of information identifying the charge on each end. In the
model, SM particles consist of three strands with spin states corresponding to
wrapped states of the strands. SM particles in this wrapped preon model can be
approximated by preon bound states in non-local dynamics based on three-preon
Bethe-Salpeter equations with instantaneous three-preon interactions. The model
can be falsified by data from the Large Hadron Collider because it generates
baryon asymmetry without axions, and does not allow more than three generations
of SM fermions.
