In [[Grand_unification_theory|grand unified theories]] of the SU(5) or SO(10) type, there is a mass relation predicted between the [[electron]] and the [[down quark]], the [[muon]] and the [[strange quark]] and the [[tau lepton]] and the [[bottom quark]] called the '''Georgi-Jarlskog mass relations'''. The relations were formulated by [[Howard Georgi]] and [[Cecilia Jarlskog]].<ref>Georgi H., Jarlskog C.

This is a preview for the new MathML rendering mode (with SVG fallback), which is availble in production for registered users.

If you would like use the MathML rendering mode, you need a wikipedia user account that can be registered here [[1]]

  • Only registered users will be able to execute this rendering mode.
  • Note: you need not enter a email address (nor any other private information). Please do not use a password that you use elsewhere.

Registered users will be able to choose between the following three rendering modes:

MathML


Follow this link to change your Math rendering settings. You can also add a Custom CSS to force the MathML/SVG rendering or select different font families. See these examples.

Demos

Here are some demos:
