Discussion: Fitting the exotic hadron spectrum with an additional quark

Thursday 19 Oct 2023, 14:00 → 15:30 Europe/Zurich

Lorenzo Capriotti (Università e INFN, Bologna (IT)), Mengzhen Wang (Università degli Studi e INFN Milano (IT))

This is an invited talk given by Scott Chapman, to discuss about the idea of explaining the exotic-hadron spectrum by introducing a new quark flavor. 

The talk would cover:

1.    Mapping exotic hadrons to mesons and baryons

2.    W interactions of the additional quark

3.    Z interactions of the additional quark

4.    Cancelling gauge anomalies

5.    Reproducing observed production and decay of exotic hadrons

6.    Addressing experiments that rule out an additional quark

7.    Alternative non-SM explanations for a few experiments

8.    Predictions testable by LHCb (and other experiments)

The paper is: [arXiv: 2203.03007] Fitting the exotic hadron spectrum with an additional quark
