BSM reach of rare charm decays, including the rising star $Λ_{c} \to p μ^{+} μ^{-}$

Hector Gisbert, Gudrun Hiller, Dominik Suelmann

We perform the first global fit of rare charm transitions using recent data on $D^{0} \to μ^{+} μ^{-}$ , $D^{+} \to π^{+} μ^{+} μ^{-}$ , $Λ_{c} \to p μ^{+} μ^{-}$ and $D^{0} \to π^{+} π^{-} μ^{+} μ^{-}$ decays, including angul…

Effective field theory analysis of rare $∣Δ c ∣ = ∣Δ u ∣ = 1$ charm decays

Hector Gisbert, Gudrun Hiller, Dominik Suelmann

We perform a global analysis of $∣Δ c ∣ = ∣Δ u ∣ = 1$ transitions using recent data on $D^{0} \to μ^{+} μ^{-}$ , $D^{+} \to π^{+} μ^{+} μ^{-}$ , $Λ_{c} \to p μ^{+} μ^{-}$ , and $D^{0} \to π^{+} π^{-} μ^{+} μ^{-}$ decays…

Constraints on baryon-number-violating top-quark operators in standard model effective field theory

Hector Gisbert, Antonio Rodríguez-Sánchez, Luiz Vale Silva

Within the Standard Model Effective Field Theory framework, we set indirect constraints on top quark operators that violate baryon number by one unit above the TeV scale. We find t…

The role of dineutrino modes in the search for new physics

Hector Gisbert

Dineutrino modes offer promising searches for new physics. The potential aspects of these modes are reviewed in detail. Performing a proper combination of them, novel tests of the…

Dineutrino modes probing lepton flavor violation

Rigo Bause, Hector Gisbert, Marcel Golz +1

$S U (2)_{L}$ -invariance links charged dilepton $q ˉ q^{'} ℓ^{+} ℓ^{-}$ and dineutrino $q ˉ q^{'} ν ˉ ν$ couplings. This connection can be established using the…

Rare charm $c \to u ν ν ˉ$ dineutrino null tests for $e^{+} e^{-}$ -machines

Rigo Bause, Hector Gisbert, Marcel Golz +1

Rare $∣Δ c ∣ = ∣Δ u ∣ = 1$ transitions into dineutrinos are strongly GIM-suppressed and constitute excellent null tests of the standard model. While branching ratios of $D \to P ν ν ˉ$ …
