DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SISSAHEP/3/"
 >Non-invertible Symmetries and Confinement in 2d Adjoint QCD</a>\nby Sahan
 d Seifnashri (Stony Brook U. SCGP) as part of SISSA HEP seminars\n\n\nAbst
 ract\nAbstract: We will discuss the notion of "non-invertible symmetries" 
 that generalize group-like symmetries in QFTs. Using these generalized sym
 metries we prove the deconfinement of the fundamental quark in 2d massless
  adjoint QCD. When the adjoint quark has a small mass the theory confines 
 and the non-invertible symmetries are softly broken. We use them to analyt
 ically compute the tension of the confining strings. We will also consider
  the symmetric quartic fermion deformations that are protected by the non-
 invertible symmetries\, thus violating the ordinary notion of naturalness.
