Evaluating alternative spin scenarios of $P_{c\bar{c}}(4440)$ and $P_{c\bar{c}}(4457)$ using heavy quark symmetries

Duygu Y{\i}ld{\i}r{\i}m

Heavy quark symmetries favor J^P = 1/2 for P_c c-bar(4440) and J^P = 3/2 for P_c c-bar(4457) as D-bar* Sigma_c molecules, allowing estimates of Xi_cc(*) Sigma_c(*) states and elimination of one spin option for P_c c-bar s(4338) and P_c c-bar s(4459).

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

One spin state appears to be favored, suggesting that P_c c-bar(4440) has J^P=1/2 and P_c c-bar(4457) has J^P=3/2.

C2weakest assumption

The assumption that the P_c c-bar(4440) and P_c c-bar(4457) states are D-bar* Sigma_c molecules to which heavy quark symmetries can be directly applied.
