Action for N D0-Branes Invariant Under Gauged Galilean Transformations
J. Kluson
In this short note we formulate an action for N D0-branes that is manifestly invariant under gauged Galilean transformations. We also find its canonical form and determine first cl…
Approximate treatment of noncommutative curvature in quartic matrix model
D. Prekrat, D. Ranković, N. K. Todorović-Vasović +2
We study a Hermitian matrix model with the standard quartic potential amended by a term for fixed external matrix . This is motivated by a curvature term in…
A note on tree factorization and no particle production
Klaus Bering
We prove factorization of the generating functional of connected tree diagrams by exploring that it is the Legendre transform of the action. This theorem is then applied to the exa…
Proposal for D0-brane anti-D0-brane Action
J. Kluson
We propose an action for the D0-brane anti-D0-brane system that has its exact solution corresponding to the marginal tachyon profile defined for arbitrary constant separation of th…
The correction from double field theory
Stanislav Hronek, Linus Wulff, Salomon Zacarias
It is known that the order correction to the tree-level effective action for the bosonic and heterotic string can be described in the framework of Double Field Theory (DFT). H…
Symplectic Grassmannians, dual conformal symmetry and 4-point amplitudes in 6D
Klaus Bering, Michal Pazderka
We investigate a new algebra-based approach of finding Grassmannian formulas for scattering amplitudes. Our prime motivation is massive amplitudes of 4D SYM, and th…
