Exotic polyquark states and their properties in QCD

open access: yes, 2017
We formulate rigorous criteria for selecting diagrams to be taken into account in the analysis of potential polyquark (tetra or penta) poles in QCD. The central point of these criteria is the requirement that the Feynman diagrams for the relevant Green ...

High tin or high lead: distinctive alloying practices of the pastoral Yuhuangmiao culture in Northeast China during the first millennium BCE

open access: yesArchaeometry, Volume 67, Issue 4, Page 1040-1056, August 2025.
Abstract The Jundushan cemetery, located on the northern boundary of the present‐day Beijing, sits at a crucial nexus between the Yan and Taihang mountains linking northern and central China. This strategic location provides an interesting case for examining interactions between pastoralism and agriculture around the early half of the first millennium ...
