Determining the scale in Lattice QCD [PDF]

Proceedings of The 33rd International Symposium on Lattice Field Theory — PoS(LATTICE 2015), 2016
We discuss scale setting in the context of 2+1 dynamical fermion simulations where we approach the physical point in the quark mass plane keeping the average quark mass constant. We have simulations at four beta values, and after determining the paths and lattice spacings, we give an estimation of the phenomenological values of various Wilson flow ...

The omega-rho meson mass splitting and mixing from lattice QCD

, 2009
We compare flavour singlet and non-singlet vector mesons from first principles using lattice QCD. With N_f=2 flavours of light quark, this addresses the omega-rho mass difference. Using maximally twisted-mass lattice QCD, we are able for the first time

Understanding the Electrical Mechanisms in Aqueous Zinc Metal Batteries: From Electrostatic Interactions to Electric Field Regulation

Advanced Materials, Volume 36, Issue 3, January 18, 2024.
Advanced approaches to prohibit dendrite growth, suppress side reactions, and promote reaction kinetics of Zn metal anodes are essential for practical Zn metal batteries. In this review, the effects of electrical‐related electrostatic interaction and electrical field regulation on the Zn2+ ions migration and deposition behavior in aqueous Zn metal ...

Chiral extrapolation of the sigma resonance

Physics Letters B, 2018
We analyze results on isoscalar ππ scattering from a Nf=2+1 lattice QCD calculation by the HadronSpectrum collaboration by re-summing the two-flavor chiral scattering amplitude of the next-to-leading order in the so-called inverse amplitude method.

Modeling pion physics in the $\epsilon$-regime of two-flavor QCD using strong coupling lattice QED

, 2007
In order to model pions of two-flavor QCD we consider a lattice field theory involving two flavors of staggered quarks interacting strongly with U(1) gauge fields. For massless quarks, this theory has an $SU_L(2)\times SU_R(2) \times U_A(1)$ symmetry. By

Exploration of Wire Array Metamaterials for the Plasma Axion Haloscope

Annalen der Physik, Volume 536, Issue 1, January 2024.
Wire array metamaterials have been proposed as ideal resonators for dark matter searches at the very high masses predicted for the post‐inflation axion, offering the prospect of making resonators simultaneously of very high frequency and very large volume. A detailed exploration of the properties of such wire array metamaterials provides strong support

Lattice QCD study of the χc1→J/ψγ decay

Physics Letters B
We present the results of our lattice QCD computation of the electric (E1) and magnetic (M2) form factors relevant to the χc1→J/ψγ decay by using the gauge field configurations produced by the Extended Twisted Mass Collaboration with Nf=2+1+1 dynamical ...

Phase diagrams in nonlocal PNJL models constrained by Lattice QCD results

, 2013
Based on lattice QCD-adjusted SU(2) nonlocal Polyakov--Nambu--Jona-Lasinio (PNJL) models, we investigate how the location of the critical endpoint in the QCD phase diagram depends on the strenght of the vector meson coupling, as well as the Polyakov-loop

Advances in Searching for Galactic Axions with a Dielectric Haloscope (MADMAX)

Annalen der Physik, Volume 536, Issue 1, January 2024.
In this article the general concept of the MADMAX (Magnetized Disc and Mirror Axion experiment) is described. MADMAX is a dielectric haloscope aimed to detect dark matter axions. Recent updates of the magnet and the cryostat that will host different prototype radio frequency (RF) booster systems are presented.

Primer on Axion Physics

Annalen der Physik, Volume 536, Issue 1, January 2024.
A primer on axion physics, emphasizing an intuitive understanding of why the axion solves the strong CP problem. Abstract The canonical axion potential is reviewed, with an emphasis on the field theory underlying radial and angular modes of complex scalar fields.
