    Soft gluons and colinear gluons

    Is there a difference between soft and colinear gluons? Are soft gluons the ones with small energy, or with small PT with respect to the qqbar axe (in this case soft and colinear would have the same meaning)?

    Rules to compute Feynman Diagram with the Feynman rules

    Hello, I am trying to compute feynman diagrams with the feynman rules but I encounter some difficulties... Since the gamma matrices, spinnors, etc do not comute, the ordering of the different factor from feynman diagram has an importance. Is there some rules that say where to begin and in...

    Solving Dark Matter with SUSY Theory

    I think this is an answer to this question : the lightest supersymmetric particle (LSP) could be a massive and stable one with no color and no charge.

    Solving Dark Matter with SUSY Theory

    Hello, How could SUSY provides a candidate to dark matter since it would only appear only above the TeV scale? The galaxies' environments is at such energies? Thanks
