Papers

  1. Research paper (scientific journal) Joint Non-commutative M-branes from Open Pure Spinor Supermembrane Sota Hanazawa and Makoto Sakaguchi arXiv:1709.03711 [hep-th] 2017/09/13 Open supermembrane with a constant three-form flux in the pure spinor formalism is examined. The BRST symmetry of the open supermembrane action leads to non-commutative (NC) M-branes. In addition to the NC M5-brane with a self-dual two-form flux, we find a NC M9-brane with an electric flux and a NC M9-brane with a magnetic flux. The former reduces in the critical electric flux limit to an M2-brane on the M9-brane, while the latter reduces in the strong magnetic flux limit to infinitely many Kaluza-Klein monopoles dissolved into the M9-brane. These NC M-branes are shown to preserve a half of 32 supersymmetries.
  2. Research paper (scientific journal) Joint D-branes from Pure Spinor Superstring in AdS_5 x S^5 Background Sota Hanazawa, Makoto Sakaguchi Nuclear Physics B914 (2017) 234 914, 234-247 2016/11/18 We examine the surface term for the BRST transformation of the open pure spinor superstring in an AdS_5 x S^5 background. We find that the boundary condition to eliminate the surface term leads to a classification of possible configurations of 1/2 supersymmetric D-branes.
