概要

• 論文の詳細を見る

• Some claim that there are two independent mixing angles (θ=35.3°,-54.7°) between ^3P_1 and ^1P_1 states of heavy-light mesons in the heavy quark symmetric limit, and others claim there is only one (θ=35.3°). We clarify the difference between these two and suggest which should be adopted. General arguments on the mixing angle between ^3L_L and ^1L_L of heavy-light mesons are given in HQET and a general relation is derived in the heavy quark symmetric limit as well as that including the first-order correction in 1/m_Q.
