B {r_arrow} {eta}{prime} + X and the QCD anomaly

PDF Version Also Available for Download.

Description

Mechanisms for the observed large Br(B {r_arrow} {eta}{prime} +X{sub s}) are examined. The authors propose that the dominant fraction of the B {r_arrow} {eta}{prime} + X{sub s} rate is due mainly to b {r_arrow} sg{sup *}, where g{sup *} is an off-shell gluon, followed by g{sup *} {r_arrow} g{eta}{prime} via the anomalous coupling of the {eta}{prime} to two gluons. The calculated rate for B {r_arrow} {eta}{prime} + X{sub s} is in rough accord with experiment using a fairly constant glue-glue-{eta}{prime} form factor. This behavior of the form factor may be indicative of glueball dominance of the channel. Searches via the ... continued below

Description

Mechanisms for the observed large Br(B {r_arrow} {eta}{prime} +X{sub s}) are examined. The authors propose that the dominant fraction of the B {r_arrow} {eta}{prime} + X{sub s} rate is due mainly to b {r_arrow} sg{sup *}, where g{sup *} is an off-shell gluon, followed by g{sup *} {r_arrow} g{eta}{prime} via the anomalous coupling of the {eta}{prime} to two gluons. The calculated rate for B {r_arrow} {eta}{prime} + X{sub s} is in rough accord with experiment using a fairly constant glue-glue-{eta}{prime} form factor. This behavior of the form factor may be indicative of glueball dominance of the channel. Searches via the modes {eta}{prime}h{sup +}h{sup {minus}} (h={pi} or K) may be worthwhile. Charmonia contributions [i.e B {r_arrow} {eta}{sub c}, {psi} ({r_arrow}{eta}{prime} + X) + X{sub s}] can only account for at most 20% of the central value of the signal. Implications for B {r_arrow} {eta}{prime} + X{sub d} and for the corresponding {eta} modes are also given.
