Two Photon Width of Heavy Pseudoscalar Mesons
In this work we revisit the calculation of the two photon width of ηc, highlighting newest experimental results and updating the potential model calculation. Unlike the ηc, the ηb state hasn’t been observed yet. We will examine various theoretical predictions for the electromagnetic decay of the lightest bb bound state. We start with the two photon decay width of a pseudoscalar quark– antiquark...

متن کاملTwo-photon width of the Higgs boson
This study investigates the potential of a photon collider for measuring the two photon partial width times the branching ratio of a light Higgs boson. The analysis is based on the reconstruction of the Higgs events produced in the γγ →h process, followed by Higgs decay into a bb̄ pair. A statistical error of the measurement of the two-photon width times the bb̄ branching ratio of the Higgs boson...
متن کاملMeasuring the two-photon decay width of Intermediate-mass Higgs at a photon-photon collider
Feasibility of a measurement of the partial decay width of the intermediate-mass Higgs boson into two photons at a photon-photon collider is studied by a simulation. The QCD radiative correction for quark pair background processes is taken into account for the realistic background estimation. It is found that the two-photon decay width can be measured with the statistical error of 7.6% with abo...
