D0-D8-F1 in Massive IIA SUGRA
We present some new supersymmetric solutions of massive IIA supergravity involving D0-branes, a D8-brane and a string. For the bosonic fields we use a general ansatz with SO(8) symmetry.
متن کاملThe D0−D8 system revisited
We address a few subtle issues regarding the interacting D0-D8 system. There are two existing interpretations for the counter-intuitive non-vanishing attractive cylinder-diagram R-R potential. We improve them each by properly dealing with the divergence of potential in the R-R as well as the NS-NS sector, which has been ignored so far. We further test them by considering the D8 to carry a flux,...
متن کاملD0 Silicon Microstrip Tracker for Run Iia
One main improvement included in the D0 detector upgrade 1 for Run IIa is its central tracking system as shown in Fig. 1. It includes a 2 T superconducting solenoid, a Central scintillating Fiber Tracker (CFT) and the SMT. The SMT design is driven by two classes of events. Barrels and central disks cover the ∼ 25 cm RMS long luminous region for high pT central physics (|η| < 1.5). Forward disks...
متن کامل1/4 BPS solutions in massive IIA supergravity
We construct four kinds of 1/4 BPS solutions in massive IIA supergravity corresponding to D8-D0-F1, D8-D2, D8-D4 and D8-D6-NS5 systems. They include many known solutions as special cases. D8-D2 and D8-D4 solutions are represented by harmonic functions as usual, while the other two by solutions of non-linear differential equations. Because these four solutions can be argued in almost identical w...
متن کاملMassive Type IIA String Theory
We study conditions on general fluxes of massive Type IIA supergravity that lead to four-dimensional backgrounds with N = 1 supersymmetry. We derive these conditions in the case of SU(3)as well as SU(2)-structures. SU(3)-structures imply that the internal space is constrained to be a nearly Kähler manifold with all the turned on fluxes, and the negative cosmological constant proportional to the...
