Phase-constrained spectroscopy in the pure- reactions and
Dan Guo, Marshall B. C. Scott, Igor Strakovsky +2
Low-energy scattering provides direct access to strange-baryon spectroscopy, but conventional charged-kaon reactions mix the and amplitudes. Motivated by the…
Amplitude-Based Analysis of QED Radiative Corrections to Electroproduction of -Mesons on Protons
Isabella Illari, Andrei Afanasev, William J. Briscoe +3
A formalism for radiative correction calculations in exclusive electroproduction on the proton is presented, extending the treatment developed for the pion channel. The EXCLUR…
Baryon and Meson Excited States
L. David Roper, Igor Strakovsky
The masses of fifteen baryon sets and twenty-four meson sets of three or more equal-quantum excited states are fitted by a simple two-parameter logarithm function, $M_n = αLn(n) +…
Universal Mass Equation for Equal-Quantum Excited-States Sets II
L. David Roper, Igor Strakovsky
We extend our recent study of the universal mass equation for equal-quantum excited-states sets reported by Roper and Strakovsky~\cite{Roper:2024ovj}. The masses of twelve baryon s…
Universal Mass Equation for Equal-Quantum Excited-States Sets I
L. David Roper, Igor Strakovsky
The masses of fifteen baryon sets and twenty-four meson sets of three or more equal-quantum excited states, using Breit-Wigner PDG masses and their uncertainties at fixed for…
