The T_cc^+ is a a doubly charmed tetraquark that lies very close to the D^* D meson thresholds. As such it can be described as a molecular bound state in an effective field theory (EFT) of heavy mesons. An EFT calculation of the width is in excellent agreement with experiment and also successfully reproduces the invariant mass spectrum of the D mesons in the three body decays of the T_cc^+....
In the last years, several exotic hadrons have been observed in the charm sector; such particles cannot be interpreted as conventional baryons or mesons and are thought to be either quark bags or molecular states. To unveil their nature, it is crucial to experimentally constrain the strong force that governs the interaction between the charm hadrons and other hadrons, for instance, by...
This presentation will discuss three recent measurements conducted at BESIII of the cross-sections of electron-positron annihilation into open or hidden charm final states. The first measurement utilizes e+e- collision data collected at BESIII, spanning center-of-mass energies from the threshold to 4.95 GeV. Precise measurements of the cross-sections of e+ e- -> Ds+ Ds- have been performed....
We provide an overview of lepton flavor violation from a theoretical perspective, both using the effective field theory framework and a variety of concrete models, motivated, for example, by the observation of neutrino masses. We also discuss non-standard signatures such as light-boson emission and flavor violation by more than one unit, highlighting challenges and opportunities at future facilities.
Charged Lepton Flavor Violation (CLFV) processes are transitions involving electrons, muons, or tau leptons that do not preserve lepton family numbers, and they provide model-independent probes of new physics beyond the Standard Model. The Mu2e experiment at Fermilab will search for the CLFV neutrino-less muon-to-electron conversion in the presence of aluminum nuclei, through the detection of...
