0 A ug 2 00 4 Regge Trajectories Analysis to D ⋆ SJ ( 2317 ) ± , D SJ ( 2460 ) ± and D SJ ( 2632 ) + Mesons

چکیده
The properties of the new observed charmed strange mesons D⋆ SJ(2317) , DSJ(2460) ± and DSJ(2632) + are simply listed. The status of investigations of these states is reviewed. An analysis to these states with Regge trajectories was made. We found that D⋆ SJ(2317) ± and DSJ(2460) ± could be arranged as (0, 1), but DSJ(2632) + seems not possible to be an orbital excited tensor particle. As a byproduct, the non-strange charmed mesons including D 1(2427) and D ⋆(2637)+ were analyzed also. PACS numbers: 12.39.-x, 13.20.Gd, 13.25.Gv, 14.40.Gx

We suggest some possible interpretations for the D SJ (2632) observed by SELEX. The D SJ (2632) could be the first radial excitation of the 1 ground state Ds (2112), and its unusual decay patten might be hopefully explained by the node structure of the wave functions. In addition, the D SJ (2632) could also be a cs̄g hybrid state or a (cs)3∗ − (s̄s̄)3 (diquark-antidiquark) bound state. Very recent...

متن کاملTowards an Understanding of the New Charm and Charm-Strange Mesons
The observation of the D∗ sJ (2317), DsJ (2460), and SELEX D ∗ sJ (2632) states with properties differing considerably from what was expected has led to a renewed interest in hadron spectroscopy. In addition to these states, non-strange partners of the DsJ states have also been observed. Understanding the D∗ 0 and D ′ 1 states can provide important insights into the DsJ states. In this contribu...

With the identification of (DsJ (2317), DsJ (2460)) as the (0 , 1) doublet in the heavy quark effective field theory, we derive the light cone QCD sum rule for the coupling of eta meson with DsJ (2317)Ds and DsJ (2460)D ∗ s . Through η − π 0 mixing we calculate their pionic decay widths, which are consistent with the experimental values (or upper limits). Combining the radiative decay widths de...
متن کاملUnderstanding D ∗ Sj (2317), Dsj(2460)
I briefly review the experimental observations concerning the charmed mesons D * sJ (2317), D sJ (2460) and survey on some of the interpretations proposed in order to understand their nature. I present an analysis of their decay modes in the hypothesis that they can be identified with the scalar and axial vector s P ℓ = 1 2 + states of c¯ s spectrum (D * s0 , D ′ s1). The method is based on hea...
