Particles beyond the Standard Model (SM) can generically have lifetimes that are long compared to SM particles at the weak scale. When produced at experiments such as the Large Hadron Collider (LHC) at CERN, these long-lived particles (LLPs) can decay far from the interaction vertex of the primary proton–proton collision. Such LLP signatures are distinct from those of promptly decaying particles that are targeted by the majority of searches ...

In response to the accelerating potential of artificial intelligence (AI) to transform our lives, various governments, multilateral bodies, and other organizations have produced high-level principles and guidelines for the ethical use of AI in recent years. Despite the staggering number of such documents (over 90 by October 2019), there appears to be a relatively high degree of convergence on the level of principles. «Inclusiveness» is ...
