Cluster structure of optimal solutions in bipartitioning of small worlds
Adam Lipowski, Antonio L. Ferreira, Dorota Lipowska
Using a simulated annealing, we examine a bipartitioning of small worlds obtained by adding a fraction of randomly chosen links to a one-dimensional chain or a square lattice. Mode…
Radiogenic backgrounds in the NEXT double beta decay experiment
NEXT Collaboration, P. Novella, B. Palmeiro +88
Natural radioactivity represents one of the main backgrounds in the search for neutrinoless double beta decay. Within the NEXT physics program, the radioactivity-induced background…
Bipartitioning of directed and mixed random graphs
Adam Lipowski, Antonio Luis Ferreira, Dorota Lipowska +1
We show that an intricate relation of cluster properties and optimal bipartitions, which takes place in undirected random graphs, extends to directed and mixed random graphs. In pa…
Initial results on energy resolution of the NEXT-White detector

One of the major goals of the NEXT-White (NEW) detector is to demonstrate the energy resolution that an electroluminescent high pressure xenon TPC can achieve for high energy track…
Electroluminescence TPCs at the thermal diffusion limit
C. A. O. Henriques, C. M. B. Monteiro, D. González-Díaz +78
The NEXT experiment aims at searching for the hypothetical neutrinoless double-beta decay from the Xe isotope using a high-purity xenon TPC. Efficient discrimination of t…
High Voltage Insulation and Gas Absorption of Polymers in High Pressure Argon and Xenon Gases
L. Rogers, R. A. Clark, B. J. P. Jones +3
High pressure gas time projection chambers (HPGTPCs) are made with a variety of materials, many of which have not been well characterized in high pressure noble gas environments. A…
