Hamiltonian formulation of the D - brane action and the light - cone Hamiltonian
نویسنده
چکیده
We present the Hamiltonian formulation of the Dirichlet p-brane action. We rewrite the recently proposed quadratic D-brane action in terms of generalized shift vector and lapse function. The first class and the second class constraints are explicitly seperated for the bosonic case. We then impose the gauge conditions in such a way that only time-independent gauge transformations are left. In this gauge we obtain the light-cone Hamiltonian which is quadratic in the field momenta of scalar and vector fields. The constraints are explicitly solved to eliminate part of the canonical variables. The Dirac brackets between the remaining variables are computed and shown to be equal to simple Poisson brackets for the bosonic D-brane. The generalization to the supersymmetric action with local fermionic symmetry is also discussed. 11.25.-w, 11.10.Ef, 11.15.-q, 11.30.Pb Typeset using REVTEX ∗e-mail: [email protected]

Planar diagrams in light-cone gauge
We consider the open string vacuum amplitude determining the interaction between a stack of N D3-branes and a single probe brane. When using light cone gauge, it is clear that the sum of planar diagrams (relevant in the large-N limit) is described by the free propagation of a closed string. A naive calculation suggests that the Hamiltonian of the closed string is of the form H = H0 − gsNP̂ . The...
متن کاملTiny Graviton Matrix Theory: DLCQ of IIB Plane-Wave String Theory, A Conjecture
We conjecture that the discrete light-cone quantization (DLCQ) of strings on the maximally supersymmetric type IIB plane-wave background in the sector with J units of lightcone momentum is a supersymmetric 0 + 1 dimensional U(J) gauge theory (quantum mechanics) with PSU(2|2)×PSU(2|2)×U(1) superalgebra. The conjectured Hamiltonian for the plane-wave matrix (string) theory, the tiny graviton matr...
متن کاملNonperturbative Calculation of Scattering Amplitudes
A method for the nonperturbative calculation of scattering amplitudes and cross sections is discussed in the context of light-cone quantization. The Lanczos-based recursion method of Haydock is suggested for the computation of matrix elements of the resolvent for the light-cone Hamiltonian, from which the T -matrix can be constructed. The scattering of composite particles is handled by a genera...
متن کاملThe role of electroweak penguin and magnetic dipole QCD penguin on hadronic b Quark Decays
This research, works with the effective Hamiltonian and the quark model. Using, the decay rates of matter-antimatter of b quark was investigated. We described the effective Hamiltonian theory which was applied to the calculation of current-current (Q1,2), QCD penguin (Q3,…,6), magnetic dipole (Q8) and electroweak penguin (Q7,…,10) decay rates. The gluonic penguin structure of hadronic decays ...
متن کاملNew conditions on ground state solutions for Hamiltonian elliptic systems with gradient terms
This paper is concerned with the following elliptic system:$$ left{ begin{array}{ll} -triangle u + b(x)nabla u + V(x)u=g(x, v), -triangle v - b(x)nabla v + V(x)v=f(x, u), end{array} right. $$ for $x in {R}^{N}$, where $V $, $b$ and $W$ are 1-periodic in $x$, and $f(x,t)$, $g(x,t)$ are super-quadratic. In this paper, we give a new technique to show the boundedness of Cerami sequences and estab...
