The spectrum and strong couplings of heavy-light hybrids
The spectrum of the 0++, 0−−, 1−+ and 1+− heavy-light hybrids have been calculated in HQET. The interpolated current of the hybrid is chosen as gq̄γαG a αμT hv (x), gq̄γαγ5G a αμT hv (x) and gq̄σμαG a αμT hv (x). Some strong couplings and decay widths of the heavy-light hybrids to B(D)π are calculated by using the QCD sum rules. The mass of 0++ hybrid with gluon in TM(1−−) or TE(1+−) mode is found...
متن کاملStrong Couplings of Heavy Mesons to A Light Vector Meson in QCD
We make a detailed analysis of the BBρ(DDρ) and B∗Bρ(D∗Dρ) strong couplings gBBρ(gDDρ) and gB∗Bρ(gD∗Dρ) using QCD light cone sum rules(LCSR). The existing some negligence is pointed out in the previous LCSR calculation on gB∗Bρ(gD∗Dρ) and an updated estimate is presented. Our findings can be used to understand the behavior of the B, D → ρ semileptonic form factors at large momentum transitions....
متن کاملmeson and the light - heavy quarkonium spectrum
We compute the c ¯ b spectrum from a first principle Salpeter equation obtained in a preceding paper. For comparison we report also the heavy-light quarko-nium spectrum and the hyperfine separations previously presented only in a graphical form. Notice that all results are parameter free. The spectrum and properties of the c ¯ b systems have been calculated various times in the past in the fram...
متن کاملDecay of heavy-light hybrids in HQET sum rules
The decay widths of the 0++ and 1−+ heavy-light hybrids to B(D) and pion are calculated by using the QCD sum rules. The interpolated current of the hybrid is chosen as gq̄γαG a αμT hv (x). In order to simplify the calculation and avoid the ambiguity of three-point correlation function, a two-point correlation function between the pion and vacuum is used instead. The decay width of the 0++ → B(D)...
متن کاملThe decay of heavy-light hybrids in HQET sum rules
The decay widths of the 0++ and 1−+ heavy-light hybrids to B(D) and pion are calculated by using the QCD sum rules. The interpolated current of the hybrid is chosen as gq̄γαG a αμT hv (x). In order to avoid the infrared problem, a two point correlation function between the pion and vacuum instead of the three point correlation function between the vacuum is used. We also keep the leading order o...
