Tetra-Quark Resonances in Lattice QCD
We study qqq̄q̄-type four-quark (4Q) systems in SU(3)c anisotropic quenched lattice QCD, using the O(a)-improved Wilson (clover) fermion at β = 5.75 on 12 × 96 with renormalized anisotropy as/at = 4. For comparison, we first investigate the lowest qq̄ scalar meson from the connected diagram and find its large mass of about 1.32GeV after chiral extrapolation, and thus the lowest qq̄ scalar meson cor...
متن کاملQuark Resonances and High Et Jets.
Possible spin-3/2 quark resonances would have a significant effect on high Et jet production through their contribution to the subprocess q + q̄ → g + g. Such enhancements are compared to a, recently reported, anomaly in inclusive jet production at the CDF detector. PACS numbers: 14.80.-j, 13.87.Ce, 13.85.-t Typeset using REVTEX ∗Electronic address: [email protected] 1 The possible existe...
متن کاملTunable THz plasmon resonances in InGaAs/InP HEMT
Voltage-tunable plasmon resonances in a InGaAs/InP high electron mobility transistor (HEMT) are reported. The gate contact consisted of a 0.5 micron period metal grating formed by electron-beam lithography. Narrow-band resonant absorption of THz radiation was observed in transmission in the range 10 – 50 cm. The resonance frequency red-shifts with increasing negative gate bias as expected. Phot...
متن کاملReconciling the Light Scalar Mesons with Breit-Wigner Resonances as well as the Quark Model
Resonances appearing in hadronic scattering processes are described by a two-phase model. In the one phase, scattering products are observed, whereas the other phase describes confinement. A so-called “Resonance-Spectrum Expansion” is derived, containing expressions that resemble Breit-Wigner formulae. This method also provides a straightforward explanation for the origin of the light scalar me...
متن کاملDynamical quark effects on light quark masses
Light quark masses are calculated in lattice QCD with two degenerate flavors of dynamical quarks. The calculations are made with improved actions with lattice spacing a = 0.22-0.11 fm. In the continuum limit we find m(M&Smacr;)(ud)(2 GeV) = 3.44(+0.14)(-0.22) MeV using the pi and rho meson masses as physical input, and m(M&Smacr;)(s)(2 GeV) = 88(+4)(-6) MeV or 90(+5)(-11) MeV with the K or stra...
