A Natural Candidate of η′’s Second Radial Excitation
نویسندگان
چکیده
Recently BES collaboration observed one interesting resonance X(1835). We point out that its mass, total width, production rate and decay pattern favor its assignment as the second radial excitation of η′ meson very naturally. PACS number: 12.39.Mk, 13.25.Jx, 11.30.Er

The Glueball Candidate Η(1440) as Η Radial Excitation
The Particle Data Group decided to split the η(1440) into two states, called ηL and ηH . The η(1295) and the ηH are supposed to be the radial excitations of the η and η, respectively. The ηL state cannot be accomodated in a quark model; it cannot be a qq̄ state, however, it might be a glueball. In this contribution it is shown that that the η(1295) does not have the properties which must be expe...
متن کاملProspects for detecting an η ′ c in two photon processes
We argue that an experimental search for an η ′ c , the first radial excitation of the η c (2980), may be carried out using the two photon process e + e − → e + e − γγ → e + e − η ′ c. We estimate the partial width Γ γγ (η ′ c) and the branching fraction B(η ′ c → h), where h is an exclusive hadronic channel, and find that for h = K o s K ± π ∓ it may be possible to observe this state in two ph...
متن کاملOn the Complexion of Pseudoscalar Mesons
A strongly momentum-dependent dressed-quark mass function is basic to QCD. It is central to the appearance of a constituent-quark mass-scale and an existential prerequisite for Goldstone modes. Dyson-Schwinger equation (DSEs) studies have long emphasised this importance, and have proved that QCD's Goldstone modes are the only pseudoscalar mesons to possess a nonzero leptonic decay constant in t...
متن کاملOn the Relations between Two-photon and Leptonic Widths of Low-lying S-wave States of Charmonium
The relation between the ratio Γee(ψ ′ )/Γee(J/ψ) and Γ2γ(η ′ c)/Γ2γ(ηc), expressed in terms of the configuration mixing amplitudes induced by the contact spin-spin interaction of quarks in the ground and radial excitation states, is shown to give, after the inclusion of the newly derived relativistic corrections, the radiative η ′ cand ηc-width ratio in fair accord with recent experiments. The...
متن کاملExcited state evolution towards ligand loss and ligand chelation at group 6 metal carbonyl centres.
The photochemistry and photophysics of three model "half-sandwich" complexes (η(6)-benzophenone)Cr(CO)3, (η(6)-styrene)Cr(CO)3, and (η(6)-allylbenzene)Cr(CO)3 were investigated using pico-second time-resolved infrared spectroscopy and time-dependent density functional theory methods. The (η(6)-benzophenone)Cr(CO)3 complex was studied using two excitation wavelengths (470 and 320 nm) while the r...
