Higgs boson decay to lepton pair and photon and possible non-Hermiticity of the Yukawa interaction

V. A. Kovalchuk, A. Yu. Korchin

The production of lepton pairs in the Higgs boson decay $h \to ℓ^{+} ℓ^{-} γ$ is studied. The emphasis is put on the structure of the Higgs boson interaction with the fermions. T…

Angular distribution and asymmetries in the decay of the polarized charmed baryon $Λ_{c}^{+} \to K^{-} Δ^{++} \to K^{-} p π^{+}$

A. Yu. Korchin, V. A. Kovalchuk

Angular distribution of the final particles in the decay $Λ_{c}^{+} \to K^{-} Δ (1232)^{++} \to K^{-} p π^{+}$ of the polarized charmed baryon is discussed. Asymmetries are proposed w…

The prospect of charm quark magnetic moment determination

A. S. Fomin, S. Barsuk, A. Yu. Korchin +7

In this paper, we discuss the theoretical framework and the experimental measurements of the magnetic moment of the charm baryons. The $Λ_{c}^{+}$ magnetic moment is particularly inter…
