The value for the radius of this particle is the subject of intense debate after experiments pairing
The value for the radius of this particle is the subject of intense debate after experiments pairing it with a muon gave a much-lower-than-expected value. The delta plus baryon, which has spin 3/2, is its high-energy equivalent. Grand unified theories that don't conserve baryon number symmetry allow this particle to decay into a neutral pion and positron, but attempts to observe this decay have only succeeded in setting the half-life to at least 10 to the (*) 34 years. A cycle named for these particles that doesn't require carbon, nitrogen, or oxygen as catalysts dominates in stars around 1 solar mass; that fusion cycle is named for a "chain" of these particles and produces helium. This baryon is composed of 2 up quarks and 1 down quark. For 10 points, name this nucleon with a positive charge.
