Decay of the Higgs boson $h \to τ^{-} τ^{+} \to π^{-} ν_{τ} π^{+} ν ˉ_{τ}$ for a non-Hermitian Yukawa interaction

A. Yu. Korchin, V. A. Kovalchuk

The differential rate of the decay of the Higgs boson ( $h$ ) to a pair of $τ$ leptons with their subsequent decay in the $τ^{-} \to π^{-} ν_{τ}$ and $τ^{+} \to π^{+} ν ˉ_{τ}$ channels is stud…

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…

Decay of the Higgs boson to $τ^{-} τ^{+}$ and non-Hermiticity of the Yukawa interaction

Alexander Yu. Korchin, Vladimir A. Kovalchuk

The issue of Hermiticity of the Higgs boson interaction with fermions is addressed. A model for non-Hermitian Yukawa interaction is proposed and approximation of one fermion genera…

Angular distribution and forward-backward asymmetry of the Higgs-boson decay to photon and lepton pair

Alexander Yu. Korchin, Vladimir A. Kovalchuk

The Higgs-boson decay h -> gamma l+ l- for various lepton states l = (e, mu, tau) is analyzed. The differential decay width and forward-backward asymmetry are calculated as functio…
