P. Matlock, R.C. Rashkov, K.S. Viswanathan, Y. Yang
TL;DR
This paper calculates D-brane tension using Vacuum String Field Theory, considering tachyon fluctuations and background B-fields, confirming standard tension results in both scenarios.
Contribution
It extends the analysis of D-brane tension to include background B-fields within Vacuum String Field Theory, confirming known results.
Findings
D-brane tension matches standard values
Tachyon fluctuations reproduce expected tension
B-field background does not alter tension results
Abstract
We consider tachyonic string-field fluctuations about a Dp-brane background in the geometrical (CFT) formulation of Vacuum String Field Theory. We then extend this analysis to the case of a background B-field. We find that the standard results for D-brane tension are reproduced in both cases.
