Puzzle for the Vector Meson Threshold Photoproduction
Igor Strakovsky
High-statistics total cross sections for the vector meson photoproduction at the threshold: (from A2 at MAMI, ELPH, and CBELSA/TAPS), (from CLAS and LEPS), and…

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…
