Inclusive $B$-meson flavour-tagging algorithm at LHCb
A new algorithm is developed to identify the flavour of neutral $B$ mesons at production in $pp$ collisions by utilising all tracks from the hadronisation process. [...]

Search for heavy neutral leptons in decays of $W$ bosons produced in 13 TeV $pp$ collisions using prompt signatures in the ATLAS detector
The existence of right-handed neutrinos with Majorana masses below the electroweak scale could help address the origins of neutrino masses, the matter-antimatter asymmetry, and dark matter. [...]

Heavy Quark Pair Energy Correlators: From Profiling Partonic Splittings to Probing Heavy-Flavor Fragmentation / Barata, João (CERN) ; Brewer, Jasmine (Oxford U., Theor. Phys.) ; Lee, Kyle (MIT, Cambridge, CTP) ; Silva, João M. (Granada U. ; LIP, Lisbon ; Lisbon, IST)
We introduce heavy-flavor energy correlators, $\langle Ψ|\mathcal{E}_{\mathcal{H}}(\vec{n}_1) \mathcal{E}_{\mathcal{H}}(\vec{n}_2)|Ψ\rangle$, as a powerful observable for profiling partonic splittings and characterizing heavy-flavor fragmentation. [...]

The detection of compact binary mergers with sub-solar masses at gravitational-wave observatories could mark the groundbreaking discovery of primordial black holes (PBHs). [...]

QGP@50: More than Four Decades of Jet Quenching / Wang, Xin-Nian (CCNU, Wuhan, Inst. Part. Phys. ; Frankfurt U.) ; Wiedemann, Urs Achim (CERN)
How are high-momentum transfer processes modified when embedded in the Quark-Gluon Plasma (QGP) instead of the vacuum? How can fundamental properties of the QGP be inferred from their medium-modifications? And what can be learnt about QCD? These questions have motivated theoretical and experimental studies for more than four decades almost since the beginning of QGP research. [...]
