The ATLAS collaboration presented the result of its latest test of a key principle of the Standard Model of particle physics known as lepton flavour universality. The precision of the result is the best yet achieved by a single experiment in decays of the W boson and surpasses that of the current experimental average.

In March 2024, the CMS collaboration announced the observation of two photons creating two tau leptons in proton–proton collisions. It is the first time that this process has been seen in proton–proton collisions, which was made possible by using the precise tracking capabilities of the CMS detector. It is also the most precise measurement of the tau’s anomalous magnetic moment and offers a new way to constrain the existence of new physics.

You got 10 CMS-tasks and probably you started all 10 at once. Vbox don't like starting many machines in the same second.

Maybe the other 6 are still running. Hopefully they are running well.

VirtualBox can't detect virtualization because it is in use by another hypervisor, in most cases Window's Hyper-V
=> Disable all Hyper-V components

How will it work when it's ready for BOINC crunchers? Will there be a new option to select on Preferences and then we'll get the new executable and its WUs?

In development:
• Finish automatic retrieval and return of jobs
• Address credit issue by smart sampling of initial conditions
• Add enconding to protect against cheaters (currently only in conceptual phase)

• We need users! (not enough jobs - volunteers are eager to crunch)

The heavy-ion physics season starts for the experiments at CERN, as stable beams of lead nuclei circulate in the #LHC at the energy of 6.8 TeV (teraelectronvolts) for the first time ever,
