Discussion Overview

The discussion revolves around the existence and properties of an axial vector version of the Phi meson, specifically seeking information on its quantum numbers, decay constants, and other related data. Participants explore theoretical classifications of mesons and express uncertainty regarding available data in established resources like the PDG listings.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant inquires about the axial vector counterpart of the Phi meson, noting its quantum numbers and seeking data on its properties.
  • Another participant asserts that the Phi meson is in a 3S1 state and claims its partner is in a 1S0 state, which is a pseudoscalar, not an axial vector.
  • A participant references a previous discussion and suggests that the information sought is covered in a specific reference, questioning the inquirer’s effort to find it.
  • There is a repeated assertion regarding the classification of mesons, emphasizing the distinction between axial vector and pseudoscalar states.
  • One participant requests clarification on the classification system mentioned, expressing unfamiliarity with it and asking for reading references.
  • A later reply directs the inquirer to a specific section in a reference text, indicating a limit to the assistance offered.

Areas of Agreement / Disagreement

Participants exhibit disagreement regarding the classification of the Phi meson and its potential axial vector counterpart. There is no consensus on the existence or properties of such a meson, and the discussion remains unresolved.

Contextual Notes

Participants express uncertainty about the availability of specific data regarding meson properties in the PDG listings, indicating potential limitations in the resources consulted. The discussion also highlights ongoing investigations into the definitions of axial vector and pseudoscalar mesons.

TL;DR
Is there any information regarding the existence of an axial vector version of the phi meson ?
I only know of the Phi vector meson which is ##s\bar{s}## which has J=1, P=-. I am looking for its axial vector version (dont know by what name it should go) ie J=1, P=+.
More specifically I am looking for any data associated with it eg its LCDAs, decay constant, mass. I am not sure I can see such data in the PDG listings.
 
Physics news on Phys.org
The φ is in a 3S1 state. It's partner is therefore in a 1S0 state, which is pseudoscalar. Not an axial vector.
 
PS This is covered in the reference last time you asked a similar question. If you don't read it, how will you learn what is in it?

That thread is still closed "pending results of a misinformation investigation" about whether or not axial vector and pseudo scalar meson quark content are definitively known.
And I did go through the PDG lists back then but I really cant find any such information there regarding quark contents of the different mesons or their LCDA functions or decay constants.
Perhaps im not looking in the right place ?

Could you explain this point a bit or give me a reading reference, preferably a textbook ?
Im not familiar with this system of classifying states that you speak of.
 
See Section 8, "A Naming Scheme for Hadrons", particularly Table 8.1.

That's all the spoon-feeding I intend to do. If you have more questions, show me you have done your part.
