Has NANOGrav found first evidence for cosmic strings? / Blasi, Simone ; Brdar, Vedran ; Schmitz, Kai
The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) has recently reported strong evidence for a stochastic common-spectrum process affecting the pulsar timing residuals in its 12.5-year data set. [...]

Multiplicity dependence of (multi-)strange baryons in the canonical ensemble with phase shift corrections / Cleymans, Jean ; Lo, Pok Man ; Redlich, Krzysztof ; Sharma, Natasha
The increase in strangeness production with charged particle multiplicity, as seen by the ALICE collaboration at CERN in p-p, p-Pb and Pb-Pb collisions, is investigated in the hadron resonance gas model taking into account interactions among hadrons using S-matrix corrections based on known phase shift analyses.

Building Models of Inflation in No-Scale Supergravity / Ellis, John (King's Coll. London ; CERN ; NICPB, Tallinn) ; Garcia, Marcos A.G. (Madrid, Autonoma U.) ; Nagata, Natsumi (Tokyo U.) ; Nanopoulos, Dimitri V. (TAMU, College Station ; HARC, Woodlands ; Athens Academy) ; Olive, Keith A. (Minnesota U.) ; Verner, Sarunas (Minnesota U.)
After reviewing the motivations for cosmological inflation formulated in the formalism of supersymmetry, we argue that the appropriate framework is that of no-scale supergravity. [...]
