Recent Experience with the CMS Data Management System / Ozturk, Hasan (CERN) ; Paparrigopoulos, Panos (CERN) ; Manrique Ardila, Andres (Wisconsin U., Madison) ; Chauhan, Rahul (Wisconsin U., Madison) ; Ellis, Katy (Rutherford) ; Emmanouil, Christos (CERN) ; Kovalskyi, Dmytro (MIT) ; Vaandering, Eric Wayne (Fermilab) ; Voetberg, Margaret Grace (Fermilab) ; Wightman, Andrew Steven (Nebraska U.) /CMS Collaboration
The CMS experiment manages a large-scale data infrastructure, currently handling over 200 PB of disk and 500 PB of tape storage and transferring more than 1 PB of data per day on average between various WLCG sites. Utilizing Rucio for high-level data management, FTS for data transfers, and a variety of storage and network technologies at the sites, CMS confronts inevitable challenges due to the system's growing scale and evolving nature.

Search for electroweak production of vector-like leptons in τ-lepton and b-jet final states in pp collisions at s = 13 TeV with the ATLAS detector
A search for pair-production of vector-like leptons is presented, considering their decays into a third-generation Standard Model (SM) quark and a vector leptoquark (U1) as predicted by an ultraviolet-complete extension of the SM, referred to as the '4321' model. [...]

A Linear Collider Vision for the Future of Particle Physics / Linear Collider Vision Collaboration
In this paper we review the physics opportunities at linear e+e− colliders with a special focus on high centre-of-mass energies and beam polarisation, take a fresh look at the various accelerator technologies available or under development and, for the first time, discuss how a facility first equipped with a technology mature today could be upgraded with technologies of tomorrow to reach much higher energies and/or luminosities.
