  • Angular correlations and CP asymmetries in the decay Φ → ZZ → 4 fermions 
    Kovalchuk, V.A. (Вопросы атомной науки и техники, 2009)
    We investigate the possibility of detecting effects of CP violation in the process Φ → ZZ → 4 fermions for a most general of Φ ZZ coupling of a Higgs boson with a spin zero with a pair of Z bosons. Moreover, as the amplitude ...
  • Angular distribution and asymmetries in flavor-changing neutral-current decay B → K* l⁺ l⁻ 
    Korchin, A.Yu.; Kovalchuk, V.A.; Lazarenko, D.O. (Вопросы атомной науки и техники, 2012)
    The fully differential angular distribution for the rare flavor-changing neutral current decay Bd⁰ → K*⁰( → K⁻π⁺)e⁺e⁻ is studied. The emphasis is placed on accurate treatment of the contribution from the processes Bd⁰ → ...
  • T-odd correlations in B±→D*K*± decays 
    Kovalchuk, V.A. (Вопросы атомной науки и техники, 2007)
    We examine T violating triple product correlations in the processes B±→D* K*±, D*→Dπ⁰, Dγ, D→f, where the neutral D(D*) meson is a superposition of D⁰(D*⁰) and D⁰(D*⁰). It is shown that large T violating asymmetries (~18% ...
