Understanding D ∗ Sj (2317), Dsj(2460)
نویسنده
چکیده
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 heavy quark symmetries and Vector Meson Dominance ansatz. Comparison with present data supports the interpretation.

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...

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 byp...
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...

The resonances D sJ(2317) and DsJ(2460) which are considered to be the (0 , 1) doublet composed of charm and strange quarks have been discovered recently. Using the method of Rosner which is based on the factorization hypothesis, we calculate the lower bounds of the decay constants of these states from the branching ratios of B → DDsJ measured by Belle and Babar. Our result shows that the decay...
متن کاملProperties of the Charmed P-wave Mesons
Two broad charmed mesons, the D∗ 0 and D ′ 1, have recently been observed. We examine the quark model predictions for the D∗ 0 and D ′ 1 properties and discuss experimental measurements that can shed light on them. We find that these states are well described as the broad, j = 1/2 non-strange charmed P -wave mesons. Understanding the D∗ 0 and D ′ 1 states can provide important insights into the...
