Weakly Bound Dibaryon from SU(3)-Flavor-Symmetric QCD

JR Green, AD Hanlon, PM Junnarkar, H Wittig - Physical Review Letters, 2021 - APS
We present the first study of baryon-baryon interactions in the continuum limit of lattice QCD,
finding unexpectedly large lattice artifacts. Specifically, we determine the binding energy of …

medium-mass nuclei up to A= 48 using the current Low Energy Nuclear Physics …

Scale setting and hadronic properties in the light quark sector with ()-flavor Wilson fermions at the physical point

T Aoyama, TM Doi, T Doi, E Itou, Y Lyu, K Murakami… - Physical Review D, 2024 - APS
We report scale setting and hadronic properties for our new lattice QCD gauge configuration
set (HAL-conf-2023). We employ (2+ 1)-flavor nonperturbatively improved Wilson fermions …

Strongly bound dibaryon with maximal beauty flavor from lattice QCD

N Mathur, M Padmanath, D Chakraborty - Physical Review Letters, 2023 - APS
We report the first lattice QCD study of the heavy dibaryons in which all six quarks have the
bottom (beauty) flavor. Performing a state-of-the-art lattice QCD calculation we find clear …

A closer look in the mirror: reflections on the matter/dark matter coincidence

A Bodas, MA Buen-Abad, A Hook… - Journal of High Energy …, 2024 - Springer
A bstract We argue that the striking similarity between the cosmic abundances of baryons
and dark matter, despite their very different astrophysical behavior, strongly motivates the …
