The mass of the Higgs boson is measured in the $H→γγ$ decay channel, exploiting the high resolution of the invariant mass of photon pairs reconstructed from the decays of Higgs bosons produced in proton–proton collisions at a centre-of-mass energy $\sqrt{s}$ = 13 TeV. The dataset was collected between 2015 and 2018 by the ATLAS detector at the Large Hadron Collider, and corresponds to an integrated luminosity of 140 fb$^{−1}$. [...]

The ATLAS experiment relies on real-time hadronic jet reconstruction and $b$-tagging to record fully hadronic events containing $b$-jets. These algorithms require track reconstruction, which is computationally expensive and could overwhelm the high-level-trigger farm, even at the reduced event rate that passes the ATLAS first stage hardware-based trigger [...]

This paper reports the first ATLAS measurement of the $ {B}_s^0 → μμ$ effective lifetime. The measurement is based on the data collected in 2015–2016, amounting to 26.3 fb$^{−1}$ of 13 TeV LHC proton-proton collisions. [...]

We formulate scenario for the simultaneous enhancement of the charge of accelerated electrons, improving such characteristics as the transformer ratio, efficiency, low energy spread, and emittance of bunches of accelerated electrons in the blowout regime by the simultaneous achievement of the identical plateaus on the accelerating wakefields and other identical plateaus on the decelerating wakefields..

Fourth-generation storage rings enabled by multi-bend achromat lattices are being inaugurated worldwide and many more are planned for the next decade. These sources deliver stable ultra-high brightness radiation with unmatched levels of transverse coherence by virtue of their highly advanced magnetic lattices. [...]
