Elliptic Ruijsenaars-Schneider model via the Poisson reduction of the Affine Heisenberg Double
(Institute of Physics, 1997)
It is shown that the elliptic Ruijsenaars-Schneider model can be obtained from
the affine Heisenberg Double by means of the Poisson reduction procedure. The
dynamical r-matrix naturally appears in the construction.
Four graviton scattering amplitude from S(N) R**8 supersymmetric orbifold sigma model
(Elsevier, 1998)
In the IR limit the Matrix string theory is expected to be described by the SNR8 supersymmetric orbifold
sigma model. Recently Dijkgraaf, Verlinde and Verlinde proposed a vertex that may describe the type IIA
string ...
Green-Schwarz strings in TsT-transformed backgrounds.
(Institute of Physics, 2006)
We consider classical strings propagating in a background generated by
a sequence of TsT transformations. We describe a general procedure to derive the
Green-Schwarz action for strings. We show that the U(1) isometry ...
Some cubic couplings in type IIB supergravity on AdS(5) x S(5) and three-point functions in SYM(4) at large N
(American Physical Society, 2000)
All cubic couplings in type IIB supergravity on AdS53S5 that involve two scalar fields sI that are mixtures
of the five form field strength on S5 and the trace of the graviton on S5 are derived by using the covariant
equations ...
Non-perturbative running of the coupling from four flavour lattice QCD with staggered quarks
(2010)
Using the Schrodinger functional (SF) with a single staggered fermion field we calculate the SF
coupling in four-flavour QCD for a wide range of energies and lattice sizes up to L/a = 16.
Preliminary results for the ...
Canonical quantization of the degenerate WZ action including chiral interaction with gauge fields
(World Scientific, 1996)
Canonical quantization of the Wess-Zumino (WZ) model including chiral interaction
with gauge field is considered for the case of a degenerate action. The two-dimensional
SU(2) Yang-Mills model and the four-dimensional ...
The chirally rotated Schrodinger functional with Wilson fermions and automatic O(a) improvement
(2011)
A modified formulation of the Schrodinger functional (SF) is proposed. In the continuum it is related to the standard SF by a non-singlet chiral field rotation and therefore referred to as the chirally rotated SF (?SF). ...
Testing universality and automatic O(a) improvement in massless lattice QCD with Wilson quarks
(Proceedings of Science, 2010)
The chirally rotated Schrodinger functional provides a test bed for universality and automatic O(a)
improvement. We here report on extensive quenched simulations of lattice QCD with Wilson
quarks in the massless limit. ...
On AdS(5) x S**5 String S-matrix.
(Elsevier, 2006)
Recently two interesting conjectures about the string S-matrix on AdS5?S5 have been made. First, assuming the existence of a Hopf algebra symmetry Janik derived a functional equation for the dressing factor of the quantum ...
