We calculate the mass of J P C = 1 −+ light exotic mesons by QCD sum rules, the mass are extracted from fourquark-hybrid correlation functions. We construct several 1 −+ fourquark molecule currents and hybrid currents, and get one mass around 1.2-1.4GeV and another one around 1.45-1.67GeV. They can be identified as π1(1400) and π1(1600). We also find fourquark current commonly mix with hybrid-like currents under renormalization. The two 1 −+ states are mixed states of fourquark and hybrid.

“…where we use the BMHV scheme to calculate traces in D dimension to keep anti-commutativity of γ 5 [64,65]. By using the 50%-10% method described above, we obtain the sum rules window for τ in the range of (0.32GeV −2 , 0.62GeV −2 ) for the 1 −− mixing correlator.…”

We studyqq-hybrid mixing for the light vector mesons andqq-glueball mixing for the light scalar mesons in Monte-Carlo based QCD Laplace sum rules. By calculating the two-point correlation function of a vectorqγ µ q (scalarqq) current and a hybrid (glueball) current we are able to estimate the mass and the decay constants of the corresponding mixed "physical state" that couples to both currents. Our results do not support strong quark/gluonic mixing for either the 1 −− or the 0 ++ states.

“…To prevent such a violation, additional renormalization is needed [3] (Readers who are interested in dimensional renormalization issues can also refer to Refs. [44][45][46][47][48][49]). This will be used in the next section.…”

The dijet invariant mass distributions from the hadronic decay of unpolarized top quark (t → bW + followed by W + → ud) are calculated, including the next-to-leading order QCD radiative corrections. We treat the top decay in the complex mass scheme due to the existence of the intermediate state W boson. Our analytical expressions are also available in different dimensional regularization schemes and γ 5 strategies. Finally, in order to construct the jets, we use different jet algorithms to compare their influences on our results. The obtained dijet mass distributions from the top quark decay are useful to distinguish these dijets from those produced via other sources and to clarify the issue about the recent CDF Collaborations' W jj anomaly.
