    Construction of a Massive ABJM Theory Without Higgs Superfields

    Full text link
    A massive Aharony-Bergman-Jafferis-Maldacena (ABJM) model in N=1\mathcal{N} =1 superspace is analysed by considering a Proca type mass term into the most general Faddeev-Popov action in a covariant gauge. The presence of mass term breaks the original BRST and anti-BRST invariance of the model. Further, the symmetry of the massive ABJM model is restored by extending the BRST and anti-BRST transformations. We show that the supergauge dependence of generating functional for connected diagrams occurs in presence of mass and ghost-anti-ghost condensates in the theory.Comment: 9 pages, no figur

    N=1 super-Chern-Simons theory in Batalin-Vilkovisky formulation

    Full text link
    We analyse the Abelian N=1N=1 super-Chern-Simons model coupled to parity-preserving matter in linear and non-linear gauges with exact BRST invariance. Then we analyse the theory in field/antifield formulation to discuss the model at quantum level. Furthermore, we implement the field/antifield dependent transformation parameter to generalize the BRST symmetry of the theory. The novelty of field/antifield dependent BRST transformation is that under change of variable the Jacobian of the functional integral extends the quantum action from linear gauge to non-linear gauge. The results are established in full generality.Comment: 7 pages, no figure, Version to appear in EP

    Quantum corrections to thermodynamics of quasitopological black holes

    Full text link
    Based on the modification to area-law due to thermal fluctuation at small horizon radius, we investigate the thermodynamics of charged quasitopological and charged rotating quasitopological black holes. In particular, we derive the leading-order corrections to the Gibbs free energy, charge and total mass densities. In order to analyse the behavior of the thermal fluctuations on the thermodynamics of small black holes, we draw a comparative analysis between the first-order corrected and original thermodynamical quantities. We also examine the stability and bound points of such black holes under effect of leading-order corrections.Comment: 15 pages, 20 captioned figures, to appear in Phys. Lett.
