goedemorgen jongetjes! het is #sciencetime

.@inspirehep.net has records for about 800k @arXiv manuscripts. the average citation count for a published paper? 42 🤡

Sridhara Dasu giving a great talk on accelerator/detector synergies at the 2nd US muon collider workshop, I also learned that SLD was not just the SLAC large detector but also referred to as slow lingering death 😅 🧪⚛️

#muons! no really, it is the @muoncollider.bsky.social summer school at UChicago!

@axelmaas.bsky.social, hope you do not mind, we have been using your #COMETA talk as a test bed for the new API 😅

.@multibosons.bsky.social 's facebook page is officially live!

visiting UChicago (yay!) for the US @muoncollider.bsky.social meeting in August to talk about electroweak @multibosons.bsky.social as constituents of #muons. just discovered my session has at least four Pitt students / alumni. 🤓🤓 cannot wait for deep dish 🍕🍕🤤🤤

Kirill Melnikov giving a talk at GGI

Great talk from Kirill Melnikov about the ultimate theoretical limits/challenges for precision physics at the LHC and future colliders during our GGI muon collider workshop. ⚛️🧪

😁😁😁😁

in ~Florence~ for a workshop at GGI on #muoncolliders and suddenly landed in Bologna! 😅😅 train time

Thea Aarrestad - Detecting the rare and complex - COMETA Colloquium 25/11/2024 new #COMETA video, supported by the Comprehensive Multiboson Experiment-Theory Action (CA22130)Recording of the COMETA Colloquium on the 25th November 2024 by Tehar Aarrestad. Title: Detecting the rare and complex: Machine Learning for precision and efficiency at the LHC Abstract: As datasets in particle physics get progressively larger, algorithms to swiftly and accurately process this data have become increasingly complex. Machine Learning (ML) has emerged as a solution to tackle several of the challenges experiments face: to efficiently select and reconstruct interesting observational data, to enhance sensitivity to increasingly rare processes and to efficiently generate accurate simulations of complex physical systems. The forthcoming High Luminosity LHC (HL-LHC) will collect roughly ten times the data of the LHC, providing new opportunities for precision measurements of rare processes such as the Higgs self coupling, vector boson scattering and vector boson fusion. In this talk, I will present recent developments in ML techniques applied to event selection, reconstruction, and analysis, and discuss their impact on enhancing searches for these rare processes. I will review the pivotal role of ML in particle physics, from its contributions to the discovery of the Higgs boson in 2012 to its application in real-time event filtering in HL-LHC, where data rates will approach 5% of global internet traffic.

my goodness. the 🦋 API is sooooo much easier than twitter's. then again, if rewriting 🐦 from scratch, one would ... hope that it was easier
