A Dispersive Look at Rare -meson Semileptonic Decays
Marco Ciuchini, Marco Fedele, Ayan Paul +5
Rare semileptonic flavour-changing neutral current transitions provide stringent tests of the Standard Model. Their interpretation is limited by hadronic uncertainties, n…

Multiple dispersive bounds. II) Sub-threshold branch-cuts
Silvano Simula, Ludovico Vittorio
We apply the strategy proposed in the companion paper [1] for dealing with multiple dispersive bounds, to the case of sub-threshold branch-cuts, which is a topic addressed extensiv…

Multiple dispersive bounds. I) The z-expansion
Silvano Simula, Ludovico Vittorio
We propose the implementation of two ingredients in the phenomenological applications of the unitary approach based on the -expansion of hadronic form factors, commonly referred…
