Supersymmetry and Attractors in N = 4 Supergravity: The Superconformal Approach
Abhinava Bhattacharjee, Bindusar Sahoo
In this paper, we study the attractor mechanism for extremal, spherically symmetric black holes in pure, untruncated, N=4 Poincaré supergravity, which we demonstrate numerically.…
Only Flat Spacetime is Full BPS in Four Dimensional N=3 and N=4 Supergravity
Abhinava Bhattacharjee, Subramanya Hegde, Bindusar Sahoo
We investigate the fully supersymmetric solutions in a class of N=3 and N=4 higher derivative Poincaré supergravity theories. These class of theories are obtained within the frame…
Supersymmetric truncation of N=3 dilaton Weyl multiplet
Soumya Adhikari, Aravind Aikot, Eswar Krishnan +2
We perform all possible supersymmetric truncations of the four-dimensional N=3 dilaton Weyl multiplet, which realizes an R-symmetry , to N=2. A parti…
Scalar-Tensor multiplet in four dimensional N=2 conformal supergravity
Aravind Aikot, Bindusar Sahoo
We study various N=2 multiplets in four dimensions by looking at the supersymmetric truncation of four dimensional N=3 multiplets. Under supersymmetric truncation, the off-shell N=…
Dilaton Weyl multiplets for conformal supergravity in four dimensions
Soumya Adhikari, Aravind Aikot, Madhu Mishra +1
We construct a dilaton Weyl multiplet for conformal supergravity in four dimensions. We couple an on-shell vector multiplet to the standard Weyl multiplet and use the field…
Variant dilaton Weyl Multiplet for N=3 conformal supergravity in four dimensions
Soumya Adhikari, Aravind Aikot, Bindusar Sahoo +1
We construct a new dilaton Weyl multiplet for conformal supergravity in four dimensions. The R-symmetry realized on this dilaton Weyl multiplet is $SU(2) \times U(1…
