Charged Lepton Radiative and B-meson Double Radiative Decays in Models with Universal Extra Dimensions
Ikaros I. Bigi, George Chiladze, Gela Devidze +3
This paper addresses the role of Large Extra Dimensions in some flavor changing neutral current (FCNC) driven processes. In particular we have investigated radiative decays of char…
Radiative Leptonic B_c Decays in Effective Field Theory
George Chiladze, Adam F. Falk, Alexey A. Petrov
The recent discovery of the B_c meson by the CDF collaboration and proposed new experiments at Fermilab and CERN motivate new theoretical studies of the B_c system. Here we investi…
Hybrid Charmonium Production in B Decays
George Chiladze, Adam F. Falk, Alexey A. Petrov
We study the production of charmonium hybrids in B decays. We use the operator product expansion and nonrelativistic QCD to organize the various contributions to this process. We e…
Phenomenology of New Baryons with Charm and Strangeness
George Chiladze, Adam F. Falk
The CLEO Collaboration recently has announced the discovery of an excited charmed and strange baryon. We estimate the expected width of this new member of the Xi_c family. We discu…
Quenched Chiral Perturbation Theory for Heavy Baryons
George Chiladze
Heavy baryon chiral perturbation theory is extended to include the effects of quenching. In this framework the leading nonanalytic dependence of the heavy baryon masses on the ligh…
Quenched Chiral Perturbation Theory for Vector Mesons
Michael Booth, George Chiladze, Adam F. Falk
We develop quenched chiral perturbation theory for vector mesons made of light quarks, in the limit where the vector meson masses are much larger than the pion mass. We use this th…
