Probing the neutrino mass through semileptonic meson decays

Damir Bečirević, Claire Chevallier, Svjetlana Faifer +2

We argue that a detailed analysis of semileptonic decays can test the possibility of a massive neutrino. The key observable, related to the forward-backward asymmetry, is exactly z…

Seeking the CP-odd Higgs via $h \to η_{c, b} ℓ^{+} ℓ^{-}$

Damir Bečirević, Blaženka Melić, Monalisa Patra +1

We show that the decay rates of the Higgs boson to a pseudoscalar quarkonium and a pair of leptons, $h \to P ℓ^{+} ℓ^{-}$ ( $P \in {η_{c}, η_{b}}$ ), can be substantially enhanced in a sce…

Leptoquark model to explain the $B$ -physics anomalies, $R_{K}$ and $R_{D}$

Damir Bečirević, Svjetlana Fajfer, Nejc Košnik +1

We show that a model with a scalar leptoquark of hypercharge $Y = 1/6$ which includes the light right-handed neutrinos, can successfully describe both of the $B$ -physics anomalies, $…

Palatable Leptoquark Scenarios for Lepton Flavor Violation in Exclusive $b \to s ℓ_{1} ℓ_{2}$ modes

Damir Bečirević, Nejc Košnik, Olcyr Sumensari +1

We examine various scenarios that involve a light $O (1 T e V)$ leptoquark state and select those which are compatible with the current experimental values for $\mathcal{B}(B_s…

Lepton flavor non-universality in $b \to s ℓ^{+} ℓ^{-}$ processes

Damir Bečirević, Svjetlana Fajfer, Nejc Košnik

We explore a scenario of New Physics entering the description of $B \to K^{(*)} μμ$ decay through couplings to the operators $O_{9, 10}^{'}$ , satisfying $C_9^\prime = -…

$B ˉ \to D τ ν ˉ_{τ}$ vs. $B ˉ \to D μ ν ˉ_{μ}$

Damir Becirevic, Nejc Kosnik, Andrey Tayduganov

Recent experimental results for the ratio of the branching fractions of $B ˉ \to D^{(*)} τ ν ˉ_{τ}$ and $B ˉ \to D^{(*)} μ ν ˉ_{μ}$ decays came as a surprise and lead to a discus…
