Parametrizations of the Spin Density Matrix
Elvio Di Salvo, Ziad Jean Ajaltouni
We propose for the spin density matrix two parametrizations which automatically fulfil the non-negativity conditions, without setting any bound on the parameters. The first one rel…
The fate of vector leptoquarks: the impact of future flavour data
C. Hati, J. Kriewald, J. Orloff +1
Motivated by the recent experimental progress on the -meson decay anomalies (in particular the angular observables in ), we rely on a simplified-model approach to…
Heavy baryon wave functions, Bakamjian-Thomas approach to form factors, and observables in transitions
D. Bečirević, A. Le Yaouanc, V. Morénas +1
Motivated by the calculation of observables in the decays , as tests of Lepton Flavor Universality, we present a calculati…
New physics in meson mixing: future sensitivity and limitations
J. Charles, S. Descotes-Genon, Z. Ligeti +4
The mixing of neutral mesons is sensitive to some of the highest scales probed in laboratory experiments. In light of the planned LHCb Upgrade II, a possible upgrade of Belle II, a…
Anomalies in Be nuclear transitions and : towards a minimal combined explanation
C. Hati, J. Kriewald, J. Orloff +1
Motivated by a simultaneous explanation of the apparent discrepancies in the light charged lepton anomalous magnetic dipole moments, and the anomalous internal pair creation in $^8…
DES16C3cje: A low-luminosity, long-lived supernova
C. P. Gutiérrez, M. Sullivan, L. Martinez +89
We present DES16C3cje, a low-luminosity, long-lived type II supernova (SN II) at redshift 0.0618, detected by the Dark Energy Survey (DES). DES16C3cje is a unique SN. The spectra a…
