physics paper

↻ Kromem reposted Andy Ayrey ✔ [S icon] @AndyAyrey · 5h gpt took a break from researching flights to read a paper on arxiv. let's see what paper it rea- what the fuck??? [Screenshot within screenshot, split view: left side shows browser tabs/search results for flight sites — "s.cathaypacific.com", "skyscanner.ie", "en.wikipedi[a]" (w icon), "airnewzealand.com", "flightsfrom.com", "arxiv.org" (with red X), and text fragments "...g flight details and sources" / "...verify flight details, particu[lar...]". Right side shows an arXiv abstract page: "...from N_f = 2 lattice QCD close to the physical point" by Gunnar S. Bali, Sara Collins, Antonio Cox, Andreas Schäfer, with a "View PDF" button, and abstract text beginning "We perform a high statistics study of the J^P = 0+ and 1+ charmed-strange mesons, D*s0(2317) and Ds1(2460), respectively. The effects of the nearby DK and D*K thresholds are taken into account by employing the corresponding four quark operators. Six ensembles with N_f = 2 non-perturbatively O(a) improved clover Wilson sea quarks at a = 0.07 fm are employed, covering different spatial volumes and pion masses: linear lattice extents L/a = 24, 32, 40, 64, equivalent to 1.7 fm to 4.5 fm, are realised for m_π = 290 MeV and L/a = 48, 64 or 3.4 fm and 4.5 fm for an almost physical pion mass of 150 MeV. Through a phase shift analysis and the effective range approximation we determine the scattering lengths, couplings to the thresholds and the infinite volume masses. Differences relative to the experimental values are observed for these" [text cut off at bottom]
