DESCRIPTION:Speakers: Ivan Kostov (IPhT - Saclay)\nWe present some exact r
esults about the tree-level 3-point function of local single-trace operato
rs in the scalar sector of planar N = 4 supersymmetric Yang-Mills. Explici
t expressions are obtained for particular cases involving su(2) and su(3)
type fields\, where the 3pt function can be written as a determinant. In
the limit of large conformal weights of the operators\, the 3pt function
depends in a universal way of the three quasimomenta and the way they spli
t into a left and right piece.\n\nhttps://indico.ipmu.jp/indico/event/13/c

DESCRIPTION:Speakers: David Kosower (IPhT\, CEA-Saclay)\nThe unitarity met
hod is a key part of the set of on-shell methods for calculating gauge-the
ory amplitudes both analytically and numerically.\nThese methods have been
used successfully to obtain the one-loop amplitudes needed for a variety
of cutting-edge high-multiplicity next-to-leading order calculations for L
HC physics. In this talk\, I present the first steps in extending maximal
unitarity to a computation of two-loop amplitudes\, needed for precision
LHC calculations. I present the formalism for double-box integrals with va
rious external masses\, and aspects of the extension to slashed-box integr
als.\n\nhttps://indico.ipmu.jp/indico/event/13/contributions/361/

DESCRIPTION:Speakers: Yuji Satoh (University of Tsukuba)\nWe discuss the M
HV amplitude/null-polygonal Wilson loop \nof $ {¥cal N} =4 $ SYM at stron
g coupling. The amplitude/Wilson loop is \nevaluated by the area of minima
l surfaces in AdS\, which are analyzed \nby integral equations of the ther
modynamic Bethe ansatz (TBA) type. \nWhen the surfaces are embedded in AdS
$_{3}$ or AdS$_{4}$\, the integral \nequations are identified with the usu
al TBA equations of a two-dimensional \nintegrable model called homogeneou
s sine-Gordon (HSG) model. The HSG\nmodel is obtained by an integrable def
ormation of a coset CFT. In special cases\, \nthe associated TBA system re
duces to simpler ones for perturbed diagonal \ncoset CFTs/(W-)minimal mode
ls. Based on these facts\, we derive an analytic \nexpansion of the amplit
ude/Wilson loop around the limit where the Wilson loop \nbecomes regular p
olygonal.\n\nhttps://indico.ipmu.jp/indico/event/13/contributions/358/

DESCRIPTION:Speakers: Chihiro Matsui (University of Tokyo)\nThe supersymme
tric sine-Gordon model is known as a perturbation from the N=1 c=3/2 super
conformal field theory. The connection between these two theories has been
studied by taking the ultraviolet limit of the supersymmetric sine-Gordon
model. The N=1 superconformal field theory is the theory of a free Majora
na fermion and a free boson\, whose Hilbert space therefore consists of a
tensor product of the fermionic part and the bosonic part.\nThere exist th
ree independent sectors in the fermionic part\, each of which is obtained
as a descendant of three different primary fields characterized by differe
nt conformal weights h=1\, 1/2\, and 1/16. The sectors of h=1 and h=1/2 ca
n be combined into one superconformal sector named the Neveu-Schwarz secto
r. The h=1/16 sector is called the Ramond sector. The supersymmetric sine-
Gordon model is also obtained from a scaling limit of the spin-1 XXZ model
with alternating inhomogeneity. Although it has been pointed out that onl
y the h=1 Neveu-Schwarz sector of the supersymmetric sine-Gordon model can
be realized from the spin chain under the periodic boundary condition\, w
e found that imposing the Dirichlet boundary conditions on both ends and c
omputing the conformal dimension through the ultraviolet limit let us obta
in the other sectors with the proper choice of boundary parameters. In the
context of the corresponding spin chain\, the phase transition between th
e Neveu-Schwarz sector and the Ramond sector is obtained in a plot of magn
etic fields with respect to a boundary parameter as the separation into tw
o sectors with different periodicity.\n\nhttps://indico.ipmu.jp/indico/eve

DESCRIPTION:Speakers: Kentaroh Yoshida (Kyoto University)\nWe consider the
classical integrable structure of two-dimensional non-linear sigma models
defined on 3D Schrodinger spacetime (called the Schrodinger sigma models
). The global symmetry is SL(2)_L x U(1)_R. The SL(2)_L symmetry is enhan
ced to the Yangian Y(sl(2)). We show that the U(1)_R symmetry is enhanced
to a Jordanian twisted Yangian. Finally I will discuss the Landau-Lifshitz
limit if I have time.\n\nhttps://indico.ipmu.jp/indico/event/13/contribut
