50 Years of Quantum Chromodynamics
Franz Gross, Eberhard Klempt, Stanley J. Brodsky +92
This paper presents a comprehensive review of both the theory and experimental successes of Quantum Chromodynamics, starting with its emergence as a well defined theory in 1972-73…
Glueballs in Radiative Decays
Eberhard Klempt
The scalar glueball is observed in a coupled-channel analysis of the -wave amplitude from BESIII data on radiative decays and further data. Ten scalar isoscalar resonances…

Scalar and tensor mesons in , and
A. V. Sarantsev, E. Klempt
LHCb data on $B^0\to\jpsi π^+π^-$, $B_{s} ^0\to\jpsi π^+π^-$ and $B_{s} ^0\to\jpsi K^+K^-$ are fitted in a coupled-channel analysis jointly with data on radiative $\jpsi$ decays, $…
Note on the definitions of branching ratios of overlapping resonances
V. Burkert, V. Crede, E. Klempt +8
Branching ratios for the decay of hadrons with large width or near thresholds depend on their definition. We test different definitions and show that rather different branching rat…
Polarization observables in double neutral pion photoproduction
TAPS Collaboration, T. Seifen, J. Hartmann +73
Measurements of target asymmetries and double-polarization observables for the reaction are reported. The data were taken with the CBELSA/TAPS experiment at the ELS…
Search for the tensor glueball
E. Klempt, A. V. Sarantsev, I. Denisenko +1
The tensor glueball is searched for in BESIII data on radiative decays into and . The invariant mass distribution exhibits an enhancement that can be de…
Singlet-octet-glueball mixing of scalar mesons
Eberhard Klempt, Andrey V. Sarantsev
The mixing angles between scalar isoscalar resonances and a scalar glueball are determined from their decays into two pseudoscalar mesons. For and , at most…
