"On the definition of branching ratios for overlapping hadron resonances",

Hadron resonances are wide and may overlap. This fact renders the definition
of a branching ratio difficult. In a simulation, different definitions of
the branching ratio are compared. Branching ratios can also be defined at
the pole position. Applications of this definition for baryons and mesons
are presented.

"On the star rating of the Particle Data Group for baryon resonances".

Criteria are presented which are used to decide if published results
on baryon properties are listed in the Review of Particle Properties.
It is discussed which results go "above the line" or "below the line",
and what requirements need to be met to promote a new resonance to have
a new RPP entry or to have more stars added to a resonance.
