arXiv:2606.09216v1 Announce Type: new Abstract: In this article, the development and investigation of fast hadron shower simulation methods is presented. A test beam dataset has been recorded in 2018 at CERN with the AHCAL Technological Prototype of the CALICE Collaboration, where the calorimeter prototype was exposed to electron, muon, and negatively charged pion beams of various initial energies. The pion shower dataset, covering energies between 10 GeV and 200 GeV, has been used to...

arXiv:2606.09216v1 Announce Type: new Abstract: In this article, the development and investigation of fast hadron shower simulation methods is presented. A test beam dataset has been recorded in 2018 at CERN with the AHCAL Technological Prototype of the CALICE Collaboration, where the calorimeter prototype was exposed to electron, muon, and negatively charged pion beams of various initial energies. The pion shower dataset, covering energies between 10 GeV and 200 GeV, has been used to develop a data-driven fast simulation algorithm of the AHCAL response to pion showers. The resulting shower model demonstrates excellent agreement with measured shower observables. In addition, a method for simulating pion showers at arbitrary energies is introduced, based upon interpolation between simulated showers at neighbouring beam energies.

NASA addresses criticism over all-male crew selected for Artemis III test mission

When NASA’s Artemis III mission launches next year, the crew won’t include any women — a revelation that sparked controversy after the agency on Tuesday announced the four astronauts selected for the flight. “Not a single woman flying on Artemis III is an insane choice,” Alexandra Doten, a space influencer who goes by Astro Alexandra, posted on X on Tuesday. NASA Administrator Jared Isaacman attempted to address these criticisms head-on Wednesday.

Jeffery Lee breathes ‘sigh of relief’ after Alabama’s nitrogen execution deemed unconstitutional

A death row prisoner whose planned execution on Thursday was suddenly halted became emotional when he learned that a federal court had ruled Alabama’s use of nitrogen gas violates the constitutional ban on cruel and unusual punishment. “It’s like an expected sigh of relief in one aspect, and then you still got to stay and maintain your focus and continue to fight,” Jeffery Lee, who has been on death row for nearly three decades, told NBC News by phone Tuesday. He spoke from the William C....
