The oldest and most robust technique to search for new particles is to look for `bumps' in invariant mass spectra over smoothly falling backgrounds. We present a new extension of the bump hunt that naturally benefits from modern machine…

Using a phenomenological \={K}N interaction combined with the method of Antisymmetrized Molecular Dynamics., we predict that few-body double-\kbar nuclei, such as ppK$^-$K$^-$ and ppnK$^-$K$^-$, as well as single-\kbar nuclei, are tightly…
