Description
Baryon number (B) is a conserved quantity in the Standard Model and plays a major role in cosmology. This poster highlights an extension of the Standard Model where baryon number conservation is an integral feature of the theory through a new local $U(1)_{\rm B}$ gauge symmetry [arXiv:1304.0576 [hep-ph]]. The baryon number is not anomaly-free and cancellation of the anomalies leads to the prediction of new particles, including a fermionic DM candidate $\chi$, a leptophobic gauge boson $Z_{\rm B}$ and a new Higgs-like particle $H_{\rm B}$. We derive experimental bounds from cosmology and direct DM detection, and observe that these allow masses of the new particles below the TeV-scale, hence within reach of the LHC. After classifying various collider signatures we use Contur [2102.04377 [hep-ph]] to confront this BSM theory for the first time with LHC measurements: by quantifying the agreement between BSM events simulated with MC event generators and differential LHC measurements we further constrain the parameter space of the model.
