Abstract Accelerating classical systems that couple to a fermion-antifermion pair at the microscopic level can radiate pairs of fermions and lose energy in the process. In this work, we derive the generalization of the Larmor formula for fermion pair

Abstract We look for relations among CKM matrix elements that are not consequences of the Wolfenstein parametrization. In particular, we search for products of CKM elements raised to integer powers that approximately equal 1. We study the running of

Abstract We study the up-down asymmetries in the three-body anti-triplet charmed baryon decays of $$\mathbf{B}_{\mathbf{c}}\rightarrow \mathbf{B}_{\mathbf{n}}MM' $$ Bc→BnMM′ with the $$SU(3)_f$$ SU(3)f flavor symmetry, where $$\mathbf{B}_{\mathbf

We analyze the decay processes of Bc→BnM with the SU(3)F flavor symmetry and spin-dependent amplitudes, where Bc(Bn) and M are the anti-triplet charmed (octet) baryon and nonet meson states, respectively. In the SU(3)F approach, it is the first tim

We study the semileptonic decays Bc→Bnℓ+νℓ where Bc(n) is the anti-triplet-charmed (octet) baryon with the SU(3)f flavor symmetry and helicity formalism. In particular, we present the decay branching ratios of Bc→Bnℓ+νℓ in three scenari

We analyze the weak processes of anti-triplet charmed baryons decaying to octet baryons and mesons with the SU(3) flavor symmetry and topological quark diagram scheme. We study the decay branching ratios without neglecting the contributions from O(15

We study the non-leptonic two-body weak decays of Λb0→pM with M=(π−,K−) and (ρ−,K⁎−) in the light-front quark model under the generalized factorization ansatz. By considering the Fermi statistic between quarks and determining spin-flav

Abstract We explore the breaking effects of the SU(3) flavor symmetry in the singly Cabibbo-suppressed anti-triplet charmed baryon decays of $$\mathbf{B}_c\rightarrow \mathbf{B}_n M$$ Bc→BnM , with $$\mathbf{B}_c=(\Xi _c^0,\Xi _c^+,\Lambda _c^+)$$

Abstract We study the semileptonic and non-leptonic charmed baryon decays with SU(3) flavor symmetry, where the charmed baryons can be B c = (Ξ c 0, Ξ c +, Λ c +), B c ′ = (Σ c (++,+,0), Ξ c ′ (+,0), Ω c 0), B cc = (Ξ cc + +, Ξ cc +, Ω c
