QCD equation of state and dark matter [PDF]
, 2012 The QCD equation of state is not often discussed in cosmology. However, the relic density of weakly interacting massive particles (WIMPs) depends on the entropy and the expansion rate of the Universe when they freeze out, at a temperature in the range ...

An effective field theory calculation of the QCD corrections to weak parameters [PDF]
Nuclear Physics B, 1991 In the standard model the parameters {rho} and M{sub W}{sup 2}/M{sub Z}{sup 2}cos{sup 2}{theta} are unity at tree level. They are protected against large corrections by the so-called custodial symmetry. We investigate the symmetry breaking effect of effect of mass splittings in fermion doublets.

Complete CP-eigen bases of meson-baryon chiral lagrangian up to p 5-order
Journal of High Energy PhysicsChiral perturbation theory describes the low energy dynamics of mesons and baryons in terms of the nonlinear Goldstone boson and fermion degrees of freedom. Through the Young tensor technique, we construct the on-shell operator bases for the meson-baryon

On the three-point order parameters of chiral symmetry breaking
Journal of High Energy Physics, 2023 The nonlocal order parameters of the QCD chiral symmetry breaking, namely the nonanomalous three-point Green functions of the quark bilinears belonging to the odd intrinsic parity sector, are studied within the framework of the Resonance chiral theory ...

Small, EarlyView.Nanometer‐sized Rh clusters provide a specific reaction environment that facilitates the balanced co‐adsorption of styrene, CO, and H, thereby promoting hydroformylation. ABSTRACT The size of the reactive metal domain, termed an ‘ensemble’, in supported metal catalysts critically influences their catalytic activity.

An effective field theory of QCD at high density [PDF]
Physics Letters B, 2000 We derive a (Wilsonian) effective field theory of QCD at finite density by integrating out the states in the Dirac sea when the chemical potential $μ\ggΛ_{\rm QCD}$. The quark-gluon coupling is effectively (1+1)-dimensional and the theory contains four-quark operators which become relevant as we approach to the Fermi sea.

Effects of final state interactions on Landau singularities
Journal of High Energy PhysicsIn certain kinematic and particle mass configurations, triangle singularities may lead to line-shapes which mimic the effects of resonances. This well-known effect is scrutinized here in the presence of final-state rescattering.

MicrobiologyOpen, Volume 15, Issue 5, October 2026.Carbon quantum dots (CDs) have emerged as versatile nanoplatforms for combating biofilm‐associated infections through multiple mechanisms, including EPS disruption, membrane damage, ROS generation, and quorum sensing inhibition. This review highlights how CD physicochemical properties and surface engineering strategies influence antibiofilm activity ...
