Discussion Overview

The discussion revolves around the gluon condensate, specifically its value in SI units and how it compares to previously accepted values, such as the SVZ value. Participants inquire about experimental references and calculations related to the gluon condensate.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant asks for the currently accepted value of the gluon condensate and its difference from the SVZ value, seeking references primarily from experimental sources.
  • Another participant notes that the last calculation of the gluon condensate they encountered is outdated and not based on experimental data, suggesting that no experiments have been conducted yet.
  • A third participant provides a link to a source that may contain more current information regarding the gluon condensate.
  • A participant requests clarification on the form and value of the gluon condensate in SI units, mentioning its known value in natural units and expressing difficulty in converting it to SI units.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the value of the gluon condensate or the existence of experimental data, indicating multiple competing views and unresolved questions.

Contextual Notes

There are limitations regarding the availability of experimental data and the reliance on older calculations, which may not reflect the current understanding of the gluon condensate.

What is the currently accepted value for the gluon condensate? How much different is from SVZ value? I would appreciate any reference, mostly from experiments.

The last calculation of the gluon condensate I've seen is pretty old: http://www.iop.org/EJ/abstract/0954-3899/20/6/001" , and is also not from experiment. I was under the impression that no such experiments existed yet though.

http://marcofrasca.wordpress.com/2009/03/30/gluon-condensate/" may have something more current though.

Can anybody tell me what is the form and value of the Gluon Condensate in the SI units? Its value in the natural units is (300Mev)^4, but I have some problems to obtain its form in SI units (in h and c).
