The analytical forms of the interaction potentials between one S-wave and one P-wave heavy mesons as well as the potentials between two P-wave heavy mesons are deduced based on a chiral quark model. Our results explicitly show the attractive property between two heavy mesons. Consequently, a series of possible molecular states are obtained. It is expected that our study might shed some light on the popular discussions of the newly observed XYZ states. 12.40.Yx, 13.75.Lb I. INTRODUCTIONThe newly discovered XYZ states, such as new charmonium-like states of X(3872) [1-4], X(3940) [5-7], X(4050) ± [8,9], X(4140) [10,11], X(4160) [12], X(4250) ± [8,9], X(4260) [13][14][15], X(4350) [10], X(4360) [16,17], X(4430) ± [18-20], X(4660) [16,17], and botomnium-like states of, are of great interests, since they cannot be simply considered as normal quarkonium of cc or bb, especially for the charged ones. For these XYZ states, many different explanations have been taken into account, including tetraquark, molecular states, hybrid charmonia, cusps, and threshold effects.In our previous works [22,23], the possible two S-wave heavy meson molecular explanations for the new resonances of X(3872), X(3940), Z b (10610) ± and Z b (10650) ± are obtained. In this paper we extend our study of the S-wave heavy meson interactions to the P-wave heavy meson interactions, and we try to explain the structures of the other XYZ states, particularly for X(4250) ± , X(4350), X(4360), X(4260), X(4430) ± . As far as X(4250) ± is concerned, it was explained as a I G (J P C ) = 0 + (1 − ) D * D 1 molecule by Close [24], however Nielsen et al. [25][26][27] considered it as a 1 + (1 − ) DD 1 molecule with QCD sum rules, while Ding [28] found that the DD 1 and D * 0D * molecules couldn't be the explanation for X(4250) ± , but for X(4260). For the latter resonance, Close [24] and Nielsen et al. [25][26][27] both agreed with Ding's conclusion. Moreover, concluded that X(4430) ± could be regarded as a tetraquark or a D * D 1 molecule. Close [24] and Ding et al. [29] confirmed this molecular explanation, however, the calculation of Liu et al. [30] disfavored the D * D 1 molecular explanation using the resonating group method in our chiral quark model.In this paper, our chiral quark model will be employed to study the heavy meson interactions. The model has been explained, in detail,. In this chiral SU(3) quark model, one-gluon-exchange (OGE), confinement potential, scalar meson exchange as well as pseudoscalar meson exchange are taken into account. Moreover, this chiral SU(3) quark model was developed into the extended chiral SU(3) quark model by introducing the vector meson exchanges. It has been proved that both models are quite successful in reproducing the spectra of the baryon ground states, the binding energy of deuteron, the nucleon-nucleon (N N ), kaon-nucleon (KN ) scattering phase shifts, and the hyperon-nucleon (Y N ) cross sections [31][32][33][34][35]. During the past years, by using the Resonating Group Method (RGM), Liu [30,36,37] and Wan...

A Two‐Step Entanglement Concentration for the Less‐Entangled Four‐Photon Cluster States

Entanglement concentration serves as an essential tool to obtain the maximally entangled states from the less‐entangled states in quantum information processing tasks. An efficient two‐step entanglement concentration protocol (ECP) is proposed to concentrate the less‐entangled four‐photon cluster states with four unknown coefficients into the maximally entangled states in this paper. The protocol utilizes parity‐check gate and photon‐polarized controlled‐Z gate, constructed with a single semiconductor quantum dot in a single optical microcavity (quantum dot‐cavity coupled system) and several linear optical elements. The discarded quantum states can be recycled in the next round concentration to achieve a higher success probability. Under conditions of strong coupling and weak side leakage rate, the ECP can tend toward ideal fidelity and efficiency. Compared to the previously proposed ECPs that utilize various auxiliary tools such as additional entangled states and complex quantum logic gates, the ECP significantly simplifies the analysis process and enables efficient implementation. Thus, the ECP is more economical and feasible in future optical systems.

“…After the pioneering studies by Blatt and Weisskopf [14] and Preston [15], barrier transmission has been studied by many researchers in terms of a static one-dimensional barrier. Depending on reaction type and expected accuracy of calculations, some theoretical methods have been developed to include, for instance, barrier fluctuation [16,17], multi-dimensional potential [18], and multi-humped fission barriers [19]. A treatment for fission involved the dynamic evolution of a system along a complicated energy surface depending on the deformation of the nucleus [20].…”

In our previous study, the applicable range of the intranuclear cascade model was successfully extended to lower incident energy (p, p x) reactions by introducing trajectory deflections and low-energy-loss process due to collective excitations. However, the model's validity was confirmed only for a 56 Fe target. In the present work we widen the applicable range of masses of the target nucleus. First, we derive an expression for the response function, which gives the probability of collective excitation strengths, to fit the distortedwave Born approximation results as a function of the target mass number and the beam energy. Second, the barrier transmission coefficient was investigated. An expression with a modified Gamow penetration factor was chosen from four phenomenological forms of one-dimensional barrier transmission coefficients. Calculations with the proposed model followed by a generalized evaporation model were carried out for double-differential cross sections of (p, p x) reactions at 30-60 MeV. Although the response function and the transmission coefficient were only parameterized approximately, the proposed model showed good agreements with experimental observations for a variety of nuclear targets from 12 C to 209 Bi.
