Although Supersymmetry (SUSY) - under certain assumptions - predicts the existence of Dark Matter (DM) candidate, the signals for DM are not specific to SUSY. Fist, how to detect DM at the LHC: DM will not be detected by the experiments directly as it is believed (reasonable assumption) to not interact with regular matter. Therefore the only way of ...

Weyl Invariance in 8d, Majorana invariance in 9D and no reductions are possible in 7D. So the minimum number of supercharges in 8,9D = $2^{8/2}/2$ complex components = 16 real supercharges. And in 7D that number is $2^{6/2}$ complex components = 16 real supercharges For further details, refer to the appendix of Polchinski vol 2

Hint: Think of way to write the Hamiltonian as $$\hat{H}~=~ -\frac{\hbar^2}{2m}\frac{d^2}{dx^2} +V(x)~=~\hat{B}^{\dagger}\hat{B} ~\geq~0$$ for some first-order differential operator $$\hat{B}~=~a(x)\frac{d}{dx} +b(x) ,$$ with suitable functions $a(x)$ and $b(x)$. Here the potential $V(x)$ is given by formula (1). Can you see what the operator ...
