“…A value of D of this order obviously cannot negate the conclusions of (12). Examining (14) closely, we see that the contribution due to a pair of on-shell D s exchanging a D * s is actually much smaller than that of (9).…”

“…Apart from lattice calculations [9], the best arenas for determining these are phenomenological approaches such as the BSW model [10] or heavy-quark effective theory [11]. Some of these parameters are also measured experimentally [12], although a somewhat large spread persists in the data. Typically, though, we have f, f * ∼ 200 MeV, f ± , V ∼ 0.6 and A 1,2 ∼ 0.25.…”

We present first calculations of new long-distance contributions to B s → γγ decay due to intermediate D s and D * s meson states. The relevant γ vertices are estimated using charge couplings and transition moment couplings. Within our uncertainties, we find that these long-distance contributions could be comparable to the known short-distance contributions. Since they have different Cabibbo-Kobayashi-Maskawa matrix-element factors, there may be an interesting possibility of observing CP violation in this decay.

“…Although various models with phenomenological parameters have been proposed so far for the hyperon interactions, it is of crucial importance at present to derive the S = −2 interaction from first principle lattice QCD simulations. Such an attempt became possible by the development of high performance computing facilities as well as the theoretical progress of the HAL QCD method [10,11,12].…”

ΛΛ and NΞ interactions from lattice QCD near the physical point

et al. 2020

The S-wave ΛΛ and N Ξ interactions are studied on the basis of the (2+1)-flavor lattice QCD simulations close to the physical point (m π 146MeV and m K 525MeV). Lattice QCD potentials in four different spin-isospin channels are extracted by using the coupled-channel HAL QCD method and are parametrized by analytic functions to calculate the scattering phase shifts. The ΛΛ interaction at low energies shows only a weak attraction, which does not provide a bound or resonant dihyperon. The N Ξ interaction in the spin-singlet and isospin-singlet channel is most attractive and lead the N Ξ system near unitarity. Relevance to the strangeness=−2 hypernuclei as well as to two-baryon correlations in proton-proton, proton-nucleus and nucleus-nucleus collisions is also discussed.

Comparison of potential models through heavy quark effective theory

I calculate heavy-light decay constants in a nonrelativistic potential model. The resulting estimate of heavy quark symmetry breaking conflicts with similar estimates from lattice QCD. I show that a semirelativistic potential model eliminates the conflict. Using the results of heavy quark effective theory allows me to identify and compensate for shortcomings in the model calculations in addition to isolating the source of the differences in the two models. The results lead to a rule as to where the nonrelativistic quark model gives misleading predictions. *
