3d Large $N$ Vector Models at the Boundary

Lorenzo Di Pietro, Edoardo Lauria, Pierluigi Niro

We consider a 4d scalar field coupled to large $N$ free or critical $O (N)$ vector models, either bosonic or fermionic, on a 3d boundary. We compute the $β$ function of the classica…

Scaling dimensions in QED $_{3}$ from the $ε$ -expansion

Lorenzo Di Pietro, Emmanuel Stamou

We study the fixed point that controls the IR dynamics of QED in $d = 4 - 2 ε$ . We derive the scaling dimensions of four-fermion and bilinear operators beyond leading order in $ε$ -e…

Scalar Multiplet Recombination at Large N and Holography

Vladimir Bashmakov, Matteo Bertolini, Lorenzo Di Pietro +1

We consider the coupling of a free scalar to a single-trace operator of a large N CFT in d dimensions. This is equivalent to a double-trace deformation coupling two primary operato…
