Evidence for a quark hard core

  • M. DerSarkissian


In a previous letter, evidence for a quark hard core was presented, but closely tied to Hagedorn’s statistical bootstrap model. To some who read the letter, it may appear that the credibility of the quark hard core rises (or falls) with the success (or failure) of the Hagedorn model (which has been modified twice since it was created in 1965). The purpose of this letter is twofold: to extend and to clarify the previous letter (where the quark hard core was introduced) ; to show clearly that the evidence for the quark hard core is independent of the Hagedorn model and that it stands on its own merits.
