The Belle II experiment at KEK in Japan considers an upgrade for the vertex detector system in line with the accelerator upgrade for higher luminosity at long shutdown 2 planned for 2028.
One ...proposal for the upgrade of the vertex detector called VTX aims to improve background robustness and reduce occupancy using small and fast pixels. VTX accommodates the OBELIX depleted monolithic active CMOS pixel sensor (DMAPS) on all five proposed layers. OBELIX is specifically developed for the VTX application and based on the TJ-Monopix2 chip initially developed to meet the requirements of the outer layers of the ATLAS inner tracker (ITk).
This paper will review recent tests of the TJ-Monopix2 chip as well as various design aspects of the OBELIX-1 chip currently under development.
We describe the planned near-term and potential longer-term upgrades of the Belle II detector at the SuperKEKB electron-positron collider operating at the KEK laboratory in Tsukuba, Japan. These ...upgrades will allow increasingly sensitive searches for possible new physics beyond the Standard Model in flavor, tau, electroweak and dark sector physics that are both complementary to and competitive with the LHC and other experiments.
A preliminary checklist of macromycetes has been previously published with reference to six governorates located in northern Tunisia. This paper provides an updated version of the inventory of ...macromycetes in Tunisia, which includes 268 species, of which seven are worldwide recognized as rare. The investigation was carried out from September 2015 to December 2018 in 13 governorates of the Tunisian territory. This updated checklist reports 145 new national species records (139 basidiomycetes and six ascomycetes) belonging to 57 genera and 13 families. Data related to distribution, ecology and preferential hosts of each recorded taxon are also provided.
