ATLAS Collaboration Sets Stronger SUSY Limits Using ML on LHC Run 2 Data

CERN's ATLAS used neural networks on LHC Run 2 data (2015–2018) to search for higgsinos/charginos via disappearing tracks and soft leptons. No SUSY found, but new exclusion limits surpass LEP constraints.

Physicist S. James Gates Jr. on Supersymmetry, Government Science, Realistic Spaceflight, and the Prospect of Life in Jupiter’s Clouds Theoretical physicist S. James Gates Jr. discusses the scientific case for and against frontier ideas—from supersymmetry and exotic propulsion to quantum computing and AI—while outlining why Mars colonization timelines are unrealistic without major breakthroughs in radiation shielding. He also examines the long arc of government-backed research, the role of DARPA-style blue-sky innovation, and why microbial life in Jupiter’s atmosphere remains a defensible hypothesis.

Composite objects in quantum (super)gravity It has been a long entertained idea that self-bound gravitons, so-called geons, could be a dark matter candidate or form (primordial) black holes. The development of viable candidates for quantum grav...

While mostly summarizing arxiv.org/abs/2504.11047 they also discuss that the Brout-Englert-Higgs effect appears to also work in gravity. And that may explain why we do not see #SuperSymmetry.

This review summarizes the CMS Run 2 Supersymmetry program, detailing strategy, targeted models, analyses, and combined results constraining the SUSY landscape at 13 TeV.

Bernd von Mallinckrodt @vonmallinckrodt.bsky.social Wenn #Supersymmetrie versagt, liegt der neue Schlüssel vielleicht nicht im Teilchen, sondern in der Schwingung selbst. Die #OntologieDerSchwingung (E = S × Smax?) eröffnet eine postmaterielle Physik, in der nicht Teilchenäquivalenz, sondern Resonanz der Zustände das Fundament des Universums bildet. HEUTE AKTUELL🖖

If #Supersymmetry fails, the new key might not lie in the particle, but in the vibration itself. The #OntologyOfVibration (E = S × Sₘₐₓ²) opens the door to a post-material physics, where the foundation of the universe is not particle equivalence, but resonance of states.
