New Relations for Gauge-Theory Amplitudes [PDF]
, 2008 We present an identity satisfied by the kinematic factors of diagrams describing the tree amplitudes of massless gauge theories. This identity is a kinematic analog of the Jacobi identity for color factors.

Scattering amplitudes and the double copy in topologically massive theories
Journal of High Energy Physics, 2020 Using the principles of the modern scattering amplitudes programme, we develop a formalism for constructing the amplitudes of three-dimensional topologically massive gauge theories and gravity.

Macroscopic strings as heavy quarks: Large-N gauge theory and anti-de Sitter supergravity [PDF]
, 1998 . We study some aspects of Maldacena's large-N correspondence between ${\cal N}=4$ superconformal gauge theory on the D3-brane and maximal supergravity on AdS$_5 \times S_5$ by introducing macroscopic strings as heavy (anti-) quark probes.

Effects of chronic browsing on life‐history traits of an irruptive large herbivore population
Population Ecology, EarlyView.This study aimed to determine the relationship between diet quality, body mass, and size (hind foot length), and female reproduction and sought to identify the mechanism by which high density under severe food limitations is maintained. Our results demonstrated that sika deer introduced to Nakanoshima Island have maintained high densities through high ...

Symmetry Transformation Parameters as Classical Dynamic Variables in the Gauge Theory
St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2020 A modification of the gauge theory is proposed, in which the set of generalized coordinates is supplemented with symmetry transformation parameters, and the condition is additionally imposed on the latter, which ensures the classical character of their ...

Charge completeness and the massless charge lattice in F-theory models of supergravity
Journal of High Energy Physics, 2021 We prove that, for every 6D supergravity theory that has an F-theory description, the property of charge completeness for the connected component of the gauge group (meaning that all charges in the corresponding charge lattice are realized by massive or ...

Hydrodynamic gradient expansion in gauge theory plasmas. [PDF]
Physical Review Letters, 2013 We utilize the fluid-gravity duality to investigate the large order behavior of hydrodynamic gradient expansion of the dynamics of a gauge theory plasma system.

Population Ecology, EarlyView.This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century.

M2-brane surface operators and gauge theory dualities in Toda [PDF]
, 2014 A bstractWe give a microscopic two dimensional N$$ \mathcal{N} $$ = (2, 2) gauge theory description of arbitrary M2-branes ending on Nf M5-branes wrapping a punctured Riemann surface. These realize surface operators in four dimensional N$$ \mathcal{N} $$
