| 英文摘要 | We calculate the relativistic corrections of j/psi, including electromagnetic corrections, to chi(bj) -> j/psi j/psi in the framework of nonrelativistic qcd factorization. the relativistic effects are found to increase the lower-order prediction for the decay width by about 10%, while the electromagnetism contribution is very small, about 0.2% for chi(b0) and chi(b2). the total branching ratios are predicted to be of order 10(-5) for chi(b0,b2) -> j/psi j/psi, but 10(-11) for chi(b1) -> j/psi j/psi, since there is only electromagnetism contribution in this channel. we predict it is possible to observe these reactions in lhc. |
