Charged Lepton Flavor Violation
Sacha Davidson, Bertrand Echenard, Robert H. Bernstein +2
This reports summarizes the activities of the Charged Lepton Flavor Violation group of the 2022 Community Summer Study. Charged lepton flavor violating reactions provide unique inf…
What is Leading Order for LFV in SMEFT?
Marco Ardu, Sacha Davidson
Upcoming searches for lepton flavour change (LFV) aim to probe New Physics(NP) scales up to TeV, implying that they will be sensitive to NP at lower scales that is sup…
Probing contact interactions with conversion
Sacha Davidson, Yoshitaka Kuno, Yuichi Uesaka +1
Contact interactions of a muon, an electron and two photons can contribute to the decay , but also to the conversion of a muon into an electron in the electric field of…
Charged lepton flavour change and Non-Standard neutrino Interactions
Sacha Davidson, Martin Gorbahn
Non-Standard neutrino Interactions (NSI) are vector contact interactions involving two neutrinos and two first generation fermions, which can affect neutrino propagation in matter.…
Selecting mu -> e Conversion Targets to distinguish Lepton Flavour-Changing Operators
Sacha Davidson, Yoshitaka Kuno, Masato Yamanaka
The experimental sensitivity to conversion on nuclei is set to improve by four orders of magnitude in coming years. However, various operator coefficients add coherently i…
Axion absorption and the spin temperature of primordial hydrogen
Adrien Auriol, Sacha Davidson, Georg Raffelt
An absorption dip in the spectrum of the cosmic microwave background observed by the EDGES experiment suggests an unexplained reduction of the hydrogen spin temperature at cosmic r…
