16 Jun 2017 | | Abstract: | In this work, the pion-induced $f_1(1285)$ production off a nucleon target is
investigated in an effective Lagrangian approaches with an interpolating
Reggeized treatment in a large range of the pion-beam momentum from threshold
up to several tens of GeV. The $s$-channel, $u$-channel, and $t $%-channel Born
terms are included to calculate production cross sections. An interpolating
Reggeized treatment is applied to $t$ channel, which is found important to
reproduce the behavior of the existent experimental total cross sections at
both low ($lesssim$ 8 GeV) and high pion-beam momenta ($gtrsim$ 8 GeV). It is
found that the $t$-channel contribution is dominant in the pion-induced
$f_1(1285)$ production at low momenta and still dominant at very forward angles
at high beam momentum. The $u$-channel contribution becomes more and more
important with the increase of pion-beam momentum and can not be neglected at
momenta higher than 10 GeV, especially at backward angles. The differential
cross sections are predicted with the model fixed by the fitting existent
experimental data. The results are helpful to the possible experiments at
J-PARC and COMPASS. | | Source: | arXiv, 1706.5202 | | Services: | Forum | Review | PDF | Favorites | |
