Electroweak precision physics via angular distributions in hadronic decays
E. Estrada, E. Passemar, S. Paz +2
Hadronic tau decays provide a unique low-energy laboratory for the charged-current interaction between quarks and leptons. Their use as an electroweak precision sector is, however,…
Scalable and Efficient Continual Learning from Demonstration via a Hypernetwork-generated Stable Dynamics Model
Sayantan Auddy, Jakob Hollenstein, Matteo Saveriano +2
Robots capable of learning from demonstration (LfD) must exhibit stability while executing learned motion skills. To be effective in the real world, they should also remember multi…
Probing baryon number with missing energy
Gudrun Hiller, Antonio RodrÃguez-Sánchez, Daniel Wendler
Quark portal interactions with a light singlet fermion make baryon number testable through missing transverse energy (MET). We find that present LHC data constrain scale…
On the Charm Contribution to the Muon Light-by-Light
Johan Bijnens, Nils Hermansson-Truedsson, Antonio RodrÃguez-Sánchez
We combine existing perturbative results to show that a precise analytic determination of the charm-quark contribution to the hadronic light-by-light (HLbL) part of the muon anomal…
The Pion Sum Rule beyond the Chiral Limit
Johan Bijnens, Nils Hermansson-Truedsson, Antonio RodrÃguez-Sánchez
The difference between the charged and neutral pion masses can be predicted from a well-known dispersion relation involving an infinite-energy integral over experimental data, the…
Beyond Form Factors: Precise Angular Tests in Hadronic Decays
E. Estrada, E. Passemar, S. Paz +2
Semileptonic decays mainly proceed via interactions between charged lepton and quark currents. The hadronization of the quark current is intrinsically nonperturbative and gene…
