TL;DR: In this paper, the authors study constraints imposed by two proposed string Swampland criteria on cosmology and find that inflationary models are generically in tension with these two criteria, and they argue that the universe will undergo a phase transition within a few Hubble times.

TL;DR: In this article, the authors present the second volume of the Future Circular Collider Conceptual Design Report, devoted to the electron-positron collider FCC-ee, and present the accelerator design, performance reach, a staged operation scenario, the underlying technologies, civil engineering, technical infrastructure, and an implementation plan.

TL;DR: In this paper, the authors describe the detailed design and preparation of a construction project for a post-LHC circular energy frontier collider in collaboration with national institutes, laboratories and universities worldwide, and enhanced by a strong participation of industrial partners.

TL;DR: In this article, the physics opportunities of the Future Circular Collider (FC) were reviewed, covering its e+e-, pp, ep and heavy ion programs, and the measurement capabilities of each FCC component, addressing the study of electroweak, Higgs and strong interactions.

TL;DR: In this paper, a new mechanism for producing the correct relic abundance of dark photon dark matter over a wide range of its mass, extending down to 10 − 20 eV, is presented.
