89. Physics Beyond the SM : The case of vector-like qiarks.

Gustavo Branco

9/25/25, 9:00 AM

We argue that VLQ are a plausible extension of the SM, and we point out a similarity
between VLQ and right-handed neutrinos entering in the seesaw mechanism type one.

69. Rare decays with missing energy and light invisible scalars

Prof. German Valencia (Monash University)

Plenary

We discuss possible light invisible scalars in the context of rare decays with missing energy. We first explore the windows remaining in B to K + inv and K to pi + inv decay modes. We construct simple UV-complete extensions and discuss some resulting phenomenology in parameter regions where the scalars are consistent with dark matter constraints.
