We investigate the simplest models where baryon and lepton numbers are defined as local symmetries spontaneously broken at the low scale and discuss the implications for cosmology. We define the simplest anomaly-free theory for spontaneous baryon and lepton number violation which predicts the existence of lepto-baryons. In this context we study the new sphaleron condition on the chemical potentials and show the relation between the present baryon asymmetry and the B-L asymmetry generated in the early universe. The properties of the cold dark matter candidate for which stability is a natural consequence from symmetry breaking are briefly discussed.

Baryon number violating hydrogen decay
Baryon-number-violating hydrogen decays into photons, leptons, or mesons all have lower bounds on their inverse partial widths exceeding 10^44 years.

Quark-universal $U(1)$ breaking scalar at the LHC
In a quark-universal U(1)_B model, the scalar φ that breaks the symmetry can be discovered first through its diphoton decay, and its rate can explain the 95 GeV diphoton excess.

Local Baryon Number at the LHC
A TeV-scale local baryon number theory predicts long-lived charged fermions with kinked-track signatures, multi-lepton events, and a small h->gamma ZB branching ratio, with current LHC data still leaving large allowed...

Gauging the accidental symmetries of the Standard Model, and implications for the flavour anomalies
Gauging an almost arbitrary combination of baryon number, lepton numbers and hypercharge, with three new singlet fermions, yields a Z' framework that can explain the B decay flavour anomalies with a universal axial co...

Probing Leptophobic Dark Sectors via Gravitational Wave Signatures
A gauged U(1)_B extension of the Standard Model is claimed to produce observable gravitational waves from a first-order phase transition, with dark matter around 8-12 TeV.
