Dbrane Decay in TwoDimensional String Theory
, 2003
"... We consider unstable D0branes of two dimensional string theory, described by the boundary state of Zamolodchikov and Zamolodchikov [hepth/0101152] multiplied by the Neumann boundary state for the time coordinate t. In the dual description in terms of the c = 1 matrix model, this D0brane is descri ..."

is described by a matrix eigenvalue on top of the upside down harmonic oscillator potential. As suggested by McGreevy and Verlinde [hepth/0304224], an eigenvalue rolling down the potential describes Dbrane decay. As the eigenvalue moves down the potential to the asymptotic region it can be described as a free
1 Dbrane decay and Hawking Radiation ∗
, 1997
"... Tree level decay amplitudes of nearBPS Dbrane configurations are known to exactly reproduce Hawking radiation rates from corresponding black holes at low energies even though the brane configurations describe semiclassical black holes only when the open string couplings are large. We show that a l ..."

Renormalization group approach to c = 1 matrix model on a circle and Dbrane decay
, 2003
"... Motivated by the renormalization group (RG) approach to c = 0 matrix model of Bre´zin and ZinnJustin, we develop a RG scheme for c = 1 matrix model on a circle and analyze how the two coupling constants in double scaling limit with critical exponent flow with the change in length scale. The RG flow ..."

The RG flow to the c = 1 fixed point can be understood as the decay of unstable D0branes with open string rolling tachyon to the 2D closed string theory
Excited Dbrane decay in Cubic String Field Theory and in Bosonic String Theory
, 2002
"... In the cubic string field theory, using the gauge invariant operators corresponding to the onshell closed string vertex operators, we have explicitly evaluated the decay amplitudes of two open string tachyons or gauge fields to one closed string tachyon or graviton up to level two. We then evaluate ..."

CP3Origins201035 HIP201015/TH Highenergy asymptotics of Dbrane decay amplitudes from Coulomb gas electrostatics
"... We study the highenergy limit of treelevel string production amplitudes from decaying Dbranes in bosonic string theory, interpreting the vertex operators as external charges interacting with a Coulomb gas corresponding to the rolling tachyon background, and performing an electrostatic analysis. ..."

DBrane Dynamics Near NS5Branes
"... We use the DiracBornInfeld action to study the real time dynamics of a Dpbrane propagating in the vicinity of NS5branes. This problem is closely related to tachyon condensation on an unstable Dbrane, with the role of the tachyon played by the radial mode on the Dbrane. As the Dbrane approache ..."

the decay of the Dbrane into closed string radiation. We propose that in our case the Dbrane decays into modes propagating in the fivebrane throat, and show that this is consistent with spacetime expectations. We also argue that for radial motions of the Dbrane deep inside the throat, the rolling process
HUEP05/35 hepth/0508071 On Dbranes in overcritical electric fields
, 2005
"... We collect some arguments for treating a Dbrane with overcritical electric field as a wellposed initial condition for a Dbrane decay. Within the field theoretical toy model of Minahan and Zwiebach we give an estimate for the condensates of the related infinite tower of tachyonic excitations. 1 ..."

Decay of Excited Dbranes
 Phys. Lett. B
, 1996
"... We calculate the leading order interactions of massless Dbrane excitations. Their 4point functions are found to be identical to those found in type I theory. The amplitude for two massless Dbrane fluctuations to produce a massless closed string is found to possess interesting new structure. As a ..."
