Total decay rate of N(1875)

  1. Apr 10, 2015 #1
    From particle data group,(http://pdg.lbl.gov/2014/listings/contents_listings.html)
    I can see the decay branching ratios of N(1875),but the total width is not found.The "Breit Wigner width " are very different.So my question is ,How do they get the branching ratio without a certain total width?

    You see all those references at the end of the PDG section on that particle? That's where the people who did the work explain how they did it.

    Which means the width is poorly known, and also the branching fractions are inconsistent. As you have many broad resonances overlapping, it is hard to assign events to specific resonances. See the references for details.
