Tracing the String: BMN correspondence at Finite J^2/N [PDF]

, 2002
Employing the string bit formalism of hep-th/0209215, we identify the basis transformation that relates BMN operators in N=4 gauge theory to string states in the dual string field theory at finite g_2=J^2/N.

String Scattering Amplitudes and Deformed Cubic String Field Theory

, 2017
We study string scattering amplitudes by using the deformed cubic string field theory which is equivalent to the string field theory in the proper-time gauge.

Form factor recursion relations at loop level

Journal of High Energy Physics, 2019
We introduce a prescription to define form factor integrands at loop level in planar N = 4 $$ \mathcal{N}=4 $$ supersymmetric Yang-Mills theory. This relies on a periodic kinematic configuration that has been instrumental to describe form factors at ...

Weyl doubling

Journal of High Energy Physics, 2020
We study a host of spacetimes where the Weyl curvature may be expressed algebraically in terms of an Abelian field strength. These include Type D spacetimes in four and higher dimensions which obey a simple quadratic relation between the field strength ...

The influence of providing perches and string on activity levels, fearfulness and leg health in commercial broiler chickens

Animal, 2015
The aim of this study was to assess the effect of providing environmental enrichment in the form of perches and string on the behaviour and welfare of commercial broiler chickens.

Topology and Wilson lines: global aspects of the double copy

Journal of High Energy Physics, 2020
The Kerr-Schild double copy relates exact solutions of gauge and gravity theories. In all previous examples, the gravity solution is associated with an abelian-like gauge theory object, which linearises the Yang-Mills equations.

String theory [PDF]

Proceedings of the National Academy of Sciences, 1998
Particle physicists have spent much of this century grappling with one basic question in various forms: what are the fundamental degrees of freedom needed to describe nature, and what are the laws that govern their dynamics? First molecules, then atoms, then “elementary particles” such as protons and neutrons all have been revealed to be composite ...

Influence of plant soil mixtures on plant vegetation

RUDN Journal of Agronomy and Animal Industries
The study was focused on investigating the effect of composition of light soil on vegetation of lettuce plants. Nowadays, reducing the density of plant substrates is becoming an important component for obtaining quality products.
