Model-independent Veltman condition, naturalness and the little hierarchy problem
Fayez Abu-Ajamieh
2022, 46(1): 013101. doi: 10.1088/1674-1137/ac2ffa
Abstract:
We adopt a bottom-up Effective Field Theory (EFT) approach to derive a model-independent Veltman condition to cancel out the quadratic divergences in the Higgs mass. We show using the equivalence theorem that all the deviations in the Higgs couplings...

Abstract:
Using an extended chromomagnetic model, we perform a systematic study of the masses of doubly heavy tetraquarks. We find that the ground states of the doubly heavy tetraquarks are dominated by the color-triplet \begin{document}$\left| {(qq)^{\bar{3}_...
Do we need to use regularization for the thermal part in the NJL model?
Kai Xue, Xiaozhu Yu, Xinyang Wang
2022, 46(1): 013103. doi: 10.1088/1674-1137/ac2ed3
Abstract:
The Nambu–Jona-Lasinio (NJL) model is one of the most useful tools for studying non-perturbative strong interactions in matter. Because it is a nonrenormalizable model, the choice of regularization is a subtle issue. In this paper, we discuss one of ...
