The Heterotic Life of the D-particle
نویسندگان
چکیده
We study the dynamics of D-particles (D0-branes) in type I' string theory and of the corresponding states in the dual heterotic description. We account for the presence of the two 8-orientifolds (8 dimensional orientifold planes) and sixteen D8-branes by deriving the appropriate quantum mechanical system. We recover the familiar condition of eight D8-branes for each 8-orientifold. We investigate bound states and compute the phase shifts for the scattering of such states and nd that they agree with the expectations from the supergravity action. In the type I' regime we study the motion transverse to the 8-orientifold and nd an interesting cancellation e ect. E-mail: [email protected] E-mail: [email protected]

Monstrous Heterotic Quantum Mechanics
A compactification of the heterotic string is considered which describes a particle propa-excited states whose dynamics is 1 + 1 dimensional. The model appears to describe D-particle dynamics in type IIA string theory on M.
متن کاملBound States of Type I D-particles and Enhanced Gauge Symmetry
Duality between the E8 × E8 heterotic string and Type I theory predicts a tower of D(irichlet)-particle bound states corresponding to perturbative heterotic string states. In the limit of infinite Type I coupling, some of these bound states become massless, giving rise to enhanced E8×E8 gauge symmetry. By taking a different infinite coupling limit, one can recover the E8 ×E8 gauge bosons of M-t...
متن کاملDeveloping heterotic groups for hybrid breeding in crop plants with emphasizing on forage crops
Exploitation of heterosis in hybrid breeding and development of synthetic cultivars is an essential procedure in plant breeding programs. The main goal of hybrid breeding programs is to select desirable parental genotypes to maximize the expression of heterosis. However, since development of high yielding hybrids and synthetic cultivars are costly and time-consuming, the accurate prediction of ...
متن کاملEffects of Alfalfa Particle Size on Ensalivation Rate, Chewing Efficiency, and Functional Specific Gravity of Particulate Matter in Hereford Steers
Six ruminally fistulated Hereford steers (body weight=414±13 kg) were used in a switch back design to determine whether two particle sizes of alfalfa hay (18.75 and 4.65 mm theoretical cut length) influenced salivary secretion during eating. The experiment carried out in two 26-d periods, with 11-d of adaptation to ration, followed by 5 d for determining the level of voluntary feed intake, 7-d ...
متن کاملOptimization of SiC particle distribution during compocasting of A356-SiCp composites using D-optimal experiment design
This paper presents an experimental design approach to the process parameter optimization for compocasting of A356-SiCp composites. Toward this end, parameters of stirring temperature, stirring time, stirring speed and SiC content were chosen and three levels of these parameters were considered. The D-optimal design of experiment (DODE) was employed for experimental design and analysis of resul...
