Orbifold equivalence for finite density QCD and effective field theory

Journal of High Energy Physics, 2011
In the large N_c limit, some apparently different gauge theories turn out to be equivalent due to large N_c orbifold equivalence. We use effective field theory techniques to explore orbifold equivalence, focusing on the specific case of a recently ...

Finite volume and partially quenched QCD-like effective field theories

Journal of High Energy Physics, 2015
We present a calculation of the meson masses, decay constants and quark-antiquark vacuum expectation value for the three generic QCD-like chiral symmetry breaking patterns SU(NF) × SU(NF) → SU(NF)V, SU(NF) → SO(NF) and SU(2NF) → Sp(2NF) in the effective ...

Effective field theories for heavy quarkonium [PDF]

, 2004
We review recent theoretical developments in heavy quarkonium physics from the point of view of Effective Field Theories of QCD. We discuss Non-Relativistic QCD and concentrate on potential Non-Relativistic QCD.

Effective Field Theories for Heavy Quarkonium

Reviews of Modern Physics, 2005
We briefly review how nonrelativistic effective field theories give us a definition of the QCD potentials and a coherent field theory derived quantum mechanical scheme to calculate the properties of bound states made by two or more heavy quarks.

Nuclear Effective Field Theories: Reverberations of the early days [PDF]

Few-body systems, 2021
Effective field theories are recognized nowadays as the framework to describe low-energy nuclear structure and reactions consistently with the underlying theory of the strong interactions, QCD. It was not always so.

Effective Field Theories and Lattice QCD for the X Y Z frontier [PDF]

Proceedings of The 38th International Symposium on Lattice Field Theory — PoS(LATTICE2021), 2021
Exotic states have been predicted before and after the advent of QCD. In the last decades they have been observed at accelerator experiments in the sector with two heavy quarks, at or above the quarkonium strong decay threshold and called X Y Z states ...

Mean field approximation for effective theories of lattice QCD [PDF]

Proceedings of The 39th International Symposium on Lattice Field Theory — PoS(LATTICE2022), 2022
For the exploration of the phase diagram of QCD, effective Polyakov loop theories derived from lattice QCD provide a valuable tool in the heavy quark mass regime. In practice, the evaluation of these theories is complicated by the appearance of long-range

Non-relativistic and potential non-relativistic effective field theories for scalar mediators [PDF]

Journal of High Energy Physics, 2021
Yukawa-type interactions between heavy Dirac fermions and a scalar field are a common ingredient in various extensions of the Standard Model. Despite of that, the non-relativistic limit of the scalar Yukawa theory has not yet been studied in full ...

Coarse graining in effective theories of lattice QCD in 1+1d and 2+1d [PDF]

Proceedings of The 38th International Symposium on Lattice Field Theory — PoS(LATTICE2021), 2021
In the strong coupling and heavy quark mass regime, lattice QCD dimensionally reduces to effective theories of Polyakov loops depending on the parameters of the original Wilson action $\beta, \kappa$ and $N_\tau$.

Interplay of nuclear physics, effective field theories, phenomenology, and lattice QCD in neutrino physics

EPJ Web of Conferences, 2022
Experiments in neutrino physics cover a wide range—from deep inelastic scattering, over long base-line oscillation experiments and low-energy coherent neutrino–nucleus scattering (CEνNS), to searches for neutrinoless double β decay (0νββ)—yet in all ...
