Accumulating Hints for Flavour Violating Higgses at the Electroweak Scale

Andreas Crivellin, Syuhei Iguro

We show that supplementing the Standard Model by only a second Higgs doublet, a combined explanation of $h \to e I ¨ $ , $h \to I^¼ I ¨ $ , $b \to s ℓ^{+} ℓ^{-}$ , the $W$ mass and $R({D^{(*)…

$b \to c$ semileptonic sum rule: exploring a sterile neutrino loophole

Motoi Endo, Syuhei Iguro, Tim Kretz +1

We investigate the $b \to c$ semileptonic sum rule in the presence of a massive sterile neutrino. Recent measurements of charged-current semitauonic $B$ -meson decays exhibit a $\sim…

$∣ V_{c b} ∣$ determinations from $B ˉ \to D^{(*)} ℓ I^ˉ ½$ decays within the SM and beyond

Wen-Sheng Fang, Syuhei Iguro, Xin-Qiang Li +3

We investigate the $∣ V_{c b} ∣$ determinations from exclusive semi-leptonic $B ˉ \to D^{(*)} ℓ I^ˉ ½$ decays, together with comprehensive fit analyses of the $\bar{B} \to D^{(*…

Semileptonic sum rules in heavy-to-light charm decays

Motoi Endo, Syuhei Iguro, Satoshi Mishima +2

We investigate semileptonic sum rules in heavy-to-light charm decays, motivated by analogous relations in $b \to c$ and $b \to u$ transitions. Focusing on the $c \to d\overline{\el…

$b \to c$ semileptonic sum rule: SU(3) $_{F}$ symmetry violation

Syuhei Iguro

To clarify possible deviations in $b \to c I ¨ I^½$ processes, the $b \to c$ semileptonic sum rule provides a valuable tool. This relation, derived based on heavy quark symmetry…

$b \to c$ semileptonic sum rule: orbitally excited hadrons

Motoi Endo, Syuhei Iguro, Satoshi Mishima

We study semileptonic sum rules for $b \to c I ¨ I^½$ transitions involving orbitally excited charm hadrons. Starting from the amplitude-level relation implied by the heavy q…
