The cosmological constant is always dimensional less?

    the cosmological constant is always dimensional less?????

    in the randall sundrum models the tension of our brane is

    [tex]T=24M^3_5 \sqrt{\frac{-\Lambda}{24M^3_5}}[/tex]...the sub index of M is the number of dimension of space time and the supercript is the power.

    ¿whats units have the planck scales [tex]M_4[/tex] and [tex]M_5[/tex]???....and then....¿whats units have the tension [tex]T[/tex]???

    Re: question

    The cosmological has dimensions of mass squared in every dimension(units c= hbar=2)

    where did you get this equation for T from?
