About All-Charm Tetraquarks in S and P Waves

Abstract

We present a quantitative analysis of masses and decays of cc c̅ c̅ tetraquarks, with diquarks and antidiquarks in S and P wave. We study explicitely the decays of the 4P−J^PC=3⁻⁻, 2⁻⁻ into 4 muons and into hidden- and open-charm mesons and estimate its width and branching ratios. Based on our results and with the present sensitivity, LHCb, CMS and ATLAS should detect the 4P−J^PC=3⁻⁻, 2⁻⁻ fully-charmed tetraquark. We note that one decay channel of the 4P−J^PC=2⁻⁻could lead to the identification of the (still controversial) χ_c1(2P).

AB  - We present a quantitative analysis of masses and decays of cc c̅ c̅ tetraquarks, with diquarks and antidiquarks in S and P wave. We study explicitely the decays of the 4P−J^PC=3^−−, 2^−− into 4 muons and into hidden- and open-charm mesons and estimate its width and branching ratios. Based on our results and with the present sensitivity, LHCb, CMS and ATLAS should detect the 4P−J^PC=3^−−, 2^−− fully-charmed tetraquark. We note that one decay channel of the 4P−J^PC=2^−−could lead to the identification of the (still controversial) χ_c1(2P).
