Exact Mass of the Charmed Lambda Baryon

Authors: D. G. Grossman

In 2006 Particle Data Group changed their FIT of the mass of the Charmed Lambda+ baryon from 2284.9 +-0.6 MeV, to 2286.46 +-0.14 MeV (an increase of 1.56 Mev), because they said the new BABAR measurement was so much better, meaning more accurate. True, the measurement is more accurate, but n-sphere factoring shows the new mass found by BABAR is probably not the mass of a Lambda(c) baryon (udc quark content), but rather it is likely the mass of a Xi(c) baryon (dsc quark content). This paper explains the arguments for the two quark content assignments, and gives an expression for the exact mass of each baryon. (Since Planck’s constant was declared exact recently, n-sphere factoring of hadron experimental masses results in expressions yielding exact theoretical masses.)
