$\tau \to \ell +$ invisible through invisible-savvy collider variables
New particles ϕ in the MeV-GeV range produced at colliders and escaping detection can be searched for at operating b- and τ-factories such as Belle II. A typical search topology involves pair-produced τs (or mesons), one of which decaying to visibles plus the ϕ, and the other providing a tag. One cr...
