Definition of "bosonic"

We calculate the bosonic boundary state corresponding to a moving fractional D p {\displaystyle p} -brane in a partially orbifoldized spacetime R 1 , d − 5 × C 2 / Z 2 {\displaystyle \mathbb {R} ^{1,d-5}\times \mathbb {C} ^{2}/\mathbb {Z} _{2}} in the presence of the Kalb-Ramond field, the U ( 1 ) {\displaystyle U(1)} gauge potential and the tachyon field.
