New limit on lorentz invariance violation

  1. Dec 27, 2009 #1
    Seasons greetings all,

    I am trying to dissect a really interesting article:


    but I am struggling with some of the more technical terms in it. I have shown it to some lecturers at my uni and even they are confused.

    For example, what is the MQGn?

    Its called the quantum gravity mass.

    All i could find on it is that it is a parameter used to scale dispersion.

    I am also struggling to understand exactly what is the result of the experiment. Its says it places a new lower limit on linear energy dependence at 1.2EPlanck, so does that mean that it was higher or lower before? Can they only test LIV time delays down to 1.2EPlanck?

    Arggghhhhh :)
