Does this norm have a specific name? References?

$begingroup$


Let $(X,mathscr{B},mu)$ be a $sigma$-finite measure space. Let $gamma$ be a probability measure on $L_2(mu)$ with $mathrm{supp} , gamma = L_2(mu)$ and existing first moment. Then



$$
f mapsto |f| := int |langle f,grangle|,gamma(mathrm{d}g)
$$



is a norm on $L_2(mu).$ Does this norm have a name? Can anyone give me some references where such normed vector spaces were studied?
