DESCRIPTION:Volodya  Kazakov\nI will give an overview of exact solution f
 or the spectrum of anomalous dimensions of planar N=4 SYM theory known as 
 Quantum Spectral Curve (QSC). I will apply it to a special\, chiral limit 
 of N=4 SYM combining week coupling and strong gamma-deformation (with imag
 inary parameters)\, recently proposed by Gurdogan and myself.  The limit 
 gives rise to a new class of non-unitary integrable CFTs of logarithmic ty
 pe in 4 dimensions\, the simplest of them being the so called bi-scalar th
 eory. It is dominated by a very limited set of integrable "fishnet" Feynma
 n graphs at any loop order. The explicit underlying structure of this inte
 grability is related to the quantum conformal SU(2\,2) Heisenberg spin cha
 in.  I will present   the analytic and numerical results for anomalous d
 imensions of BMN-type operators dominated by calculable "wheel" graphs. I 
 will also mention the precise Yangian symmetry of planar bi-scalar amplitu
 des.
