“…The papers of Refs. [2][3][4] and this work give the mass for a 2 3 P 2 state 1938, 1896, 1850, and 1870 MeV, respectively, and for its iso-vector partner is a 2 (1700) [32], the mass of K * 2 (1980) is a bit larger as a 2 3 P 2 state. We should, of course, combine the decay information of K * 2 (1980) to determine which possibility of its assignment we should take.…”

The mass spectrum of the kaon family is analyzed by the modified Godfrey-Isgur model with a color screening effect approximating the kaon as a heavy-light meson system. This analysis gives us the structure and possible assignments of the observed kaon candidates, which can be tested by comparing the theoretical results of their two-body strong decays with the experimental data. Additionally, prediction of some partial decay widths is made on the kaons still missing in experiment. This study is crucial to establishing the kaon family and searching for their higher excitations in the future.

“…Except t quark, the other quarks can form mesons, baryons ,and other hadrons. As an important part of hadron, the meson family is phenomenologically studied by many works [1][2][3][4][5][6][7][8][9]. When checking the experimental status of mesons [10], we notice an interesting phenomenon, the whole meson family with J PC = 5 ++ (with qq component, here q defines u, d, or s quark) is still missing, yet the other families for a and f meson (such as a 0 , a 1 , a 2 , a 3 , a 4 , and a 6 ) have been reported by Particle Data Group(PDG) [10].…”

In this paper, we study the spectrum and decay behavior of 5 ++ meson family which is still missing in experiment. By the modified Godfrey-Isgur model with a color screening effect, we obtain the mass spectrum of a 5 , f 5 and f ′ 5 mesons. And we predict their two-body strong decays by means of a phenomenology quark pair creation model. This study is crucial to establish J PC = 5 ++ meson family and it is also helpful to search for these states in the future.

“…We choose the continuum-discretized coupled-channel (CDCC) approach [13,14] to treat deuteron breakup in A(d, p)B reactions beyond the adiabatic aproximation. The CDCC, developed and used for local nucleontarget optical potentials only, in some cases predicts significantly different cross sections than the ADWA does [15][16][17]. Extending the CDCC to the case of nonlocal n-A and p-A potentials, in principle, could be done on the basis of the exact nonlocal ADWA formalism of Ref.…”

It has recently been reported [Phys. Rev. Lett. 117, 162502 (2016)] that (d, p) cross sections can be very sensitive to the n-p interactions used in the adiabatic treatment of deuteron breakup with nonlocal nucleon-target optical potentials. To understand to what extent this sensitivity could originate in the inaccuracy of the adiabatic approximation we have developed a leading-order localequivalent continuum-discretized coupled-channel model that accounts for non-adiabatic effects in the presence of nonlocality of nucleon optical potentials. We have applied our model to the astrophysically relevant reaction 26m Al(d, p) 27 Al using two different n-p potentials associated with the lowest and the highest n-p kinetic energy in the short-range region of their interaction, respectively. Our calculations reveal a significant reduction of the sensitivity to the high n-p momenta thus confirming that it is mostly associated with theoretical uncertainties of the adiabatic approximation itself. The non-adiabatic effects in the presence of nonlocality were found to be stronger than those in the case of the local optical potentials. These results argue for extending the analysis of the (d, p) reactions, measured for spectroscopic studies, beyond the adiabatic approximation.
