ATLAS Collaboration’s Post

Now published online: "On the application of Krylov subspace spectral methodologies to poroacoustic shock formation in an exponential class of inhomogeneous gases", authored by my soon-to-be graduating PhD student Chelsea Drum, myself, and Pedro M. Jordan (NRL), in Journal of Computational Physics--featuring the use of component-wise spectral time-stepping methods for modeling acoustic singular surfaces, at large CFL numbers with little to no need for regularization.

The ATLAS Collaboration has measured the W-boson width for the first time at the Large Hadron Collider, providing the most precise single-experiment measurement to date. https://lnkd.in/gyy8Ky25

ATLAS provides first measurement of the W-boson width at the LHC! One parameter that may hold clues about new physics phenomena is the “width” of the W boson. In a groundbreaking new result, the ATLAS Collaboration has measured the W-boson width for the first time at the LHC, providing the most precise single-experiment measurement to date.

I'm glad to share that our paper on the 𝐦𝐨𝐦𝐞𝐧𝐭 𝐜𝐨𝐧𝐬𝐭𝐫𝐚𝐢𝐧𝐞𝐝 𝐞𝐧𝐭𝐫𝐨𝐩𝐢𝐜 𝐨𝐩𝐭𝐢𝐦𝐚𝐥 𝐭𝐫𝐚𝐧𝐬𝐩𝐨𝐫𝐭 with application in particle methods has been published in the Journal of Computational Physics. Check it out here: https://lnkd.in/e3SPBJVH w./ Nicolas Hadjiconstantinou and Hossein Gorji

Happy to announce our new paper: https://lnkd.in/dCHvJWhx In this work we used Tensor Network techniques to study real-time evolution phenomena in the lattice Schwinger model (Quantum Electrodynamics in one spatial dimension discretised on the lattice). Specifically, we studied elastic and inelastic scattering of composite particles, exploring what energy threshold is required to produce particles post-collision. We calculated observables that can be directly measured in quantum simulator experiments.

Great to see this result highlighted! It is a perfect example of why fundamental detector and performance work matters, as the ultimate potential is determined by those hard and pivotal developments. On to the next challenge!

If spotting one Higgs boson is interesting, what happens when you spot two at the same time? In their new analysis, ATLAS physicists are looking for Higgs-pairs in the complex soup of particles created in their experiment. Check out our new physics briefing to learn more ⤵️

The CMS experiment has presented its first search for new physics using data from Run 3 of the Large Hadron Collider. The new study looks at the possibility of "dark photon" production in the decay of Higgs bosons in the detector.
