Environmental Dependence of Masses and Coupling Constants

چکیده
We construct a class of scalar field models coupled to matter that lead to the dependence of masses and coupling constants on the ambient matter density. Such models predict a deviation of couplings measured on the Earth from values determined in low-density astrophysical environments, but do not necessarily require the evolution of coupling constants with the redshift in the recent cosmological past. Additional laboratory and astrophysical tests of ∆α and ∆(mp/me) as functions of the ambient matter density are warranted.

Quark mass dependence of pseudo-scalar masses and coupling constants
The dependence of pseudo-scalar masses and decay constants on the sea and valence quark masses is investigated in the pseudo-Goldstone boson sector of QCD with two light quark flavours. The sea quark masses are at present in the range 1 3 ms ≤ mud ≤ 2 3 ms whereas the valence quark masses satisfy 1 2 msea ≤ mval ≤ 2msea. The values of the Gasser-Leutwyler low energy constants L4, L5, L6 and L8 ...
متن کاملQuark mass dependence of masses and decay constants of the pseudo-Goldstone bosons in QCD
The dependence of the pseudoscalar meson masses and decay constants on sea and valence quark masses is compared to next-to-leading order (NLO) Chiral Perturbation Theory (ChPT). The numerical simulations with two light dynamical quark flavors are performed with the Wilson-quark lattice action at gauge coupling β = 5.1 and hopping parameters κ = 0.176, 0.1765, 0.177 on a 16 lattice. O(a) lattice...
متن کاملQuark mass dependence of baryon properties
I discuss the quark mass dependence of various baryon properties derived from chiral perturbation theory. Such representations can eventually be used as chiral extrapolation functions when lattice data at sufficiently small quark masses become available. The quark mass dependence is encoded in loop and contact term contributions, the latter given in terms of low-energy constants. I stress the i...
متن کاملSaturation properties of nuclear matter in a relativistic mean field model constrained by quark dynamics
We have built an effective Walecka-type hadronic Lagrangian in which the hadron masses and the density dependence of the coupling constants are deduced from the quark dynamics using a Nambu-Jona-Lasinio model. The parameters of this Nambu-Jona-Lasinio model have been determined using the meson properties in the vacuum but also in the medium through the omega meson mass in nuclei measured by the...
متن کاملInvestigating the Effects of Molecular Oxygen Impurity on the Quadrupole Coupling Constants of Boron Nitride Nanotubes: Computational Studies
Density functional theory (DFT) calculations have been performed to investigating the effects of themolecular oxygen impurity on the quadrupole coupling constant (Qcc) parameters of armchair and zigzagboron nitride nanotubes (BNNTs). Optimization processes have been performed to relax the original andimpure structures of the investigated BNNTs. Afterwards, the Qcc parameters have been evaluated...
