A Determination of $α_s(m_Z)$ at aN$^3$LO$_{\bf QCD}\otimes {\bf NLO}_{\bf QED}$ Accuracy from a Global PDF Analysis
We present a determination of the strong coupling $α_s(m_Z)$ from a global dataset including both fixed-target and collider data from deep-inelastic scattering and a variety of hadronic processes, with a simultaneous determination of parton distribution functions (PDFs) based on the NNPDF4.0 methodology. This determination is performed at NNLO and approximate N$^3$LO (aN$^3$LO) perturbative QCD accuracy, including QED corrections and a photon PDF up to NLO accuracy. We extract $α_s$ using two…

The FT has consistently excellent climate coverage. This one is a bit of a depressing read, but also enlightening.
It's quite clear that the vast majority of growth in coal use is in Asia, mostly China and India, and it more than offsets the shrinking use of coal in Europe and the Americas.
My great grandfather died after a coal mining accident, my kids don't even really know what coal is. I have to hope that the trajectory away from coal will be accelerated in Asia compared to Europe.

Virtual invariants of Quot schemes of points on threefolds
We construct an almost perfect obstruction theory of virtual dimension zero on the Quot scheme parametrizing zero-dimensional quotients of a locally free sheaf on a smooth projective $3$-fold. This gives a virtual class in degree zero and therefore allows one to define virtual invariants of the Quot scheme. We compute these invariants proving a conjecture by Ricolfi. The computation is done by reducing to the toric case via cobordism theory and a degeneration argument. The toric case is solved …

Eu tava ausente do #Mastodon e voltei ao #Facebook, e agora estou desintoxicando de novo.
Mas a pergunta que sempre fica é: por que jš não veio todo mundo para o Mastodon?

Feliz de ver que o Espaço Michel #Foucault voltou ao ar:
