Prospects for detection of $Upsilon(1D) o Upsilon(1S) pi pi$ via $Upsilon(3S) o Upsilon(1D) + X$ | | Jonathan L. Rosner

14 Feb 2003 | | Journal: | Phys.Rev. D67 (2003) 097504 | | Subject: | hep-ph | | Abstract: | At least one state in the first family of D-wave $b ar b$ quarkonium levels has been discovered near the predicted mass of 10.16 GeV/$c^2$. This state is probably the one with J=2. This state and the ones with J=1 and J=3 may contribute a detectable amount to the decay $Upsilon(1D) o Upsilon(1S) pi pi$, depending on the partial widths for these decays for which predictions vary considerably. The prospects for detection of the chain $Upsilon(3S) o Upsilon(1D) + X o Upsilon pi pi + X$ are discussed. | | Source: | arXiv, hep-ph/0302122 | | Services: | Forum | Review | PDF | Favorites | |
