Searching for long-lived particles beyond the Standard Model at the Large Hadron Collider / Alimena, Juliette (Ohio State U.) ; Beacham, James (Duke U.) ; Borsato, Martino (Heidelberg U.) ; Cheng, Yangyang (Cornell U., LNS) ; Cid Vidal, Xabier (Santiago de Compostela U.) ; Cottin, Giovanna (Taiwan, Natl. Taiwan U.) ; De Roeck, Albert (CERN) ; Desai, Nishita (Tata Inst.) ; Curtin, David (Toronto U.) ; Evans, Jared A. (Cincinnati U.) et al.
Particles beyond the Standard Model (SM) can generically have lifetimes that are long compared to SM particles at the weak scale. [...]

Dreaming Awake: Disentangling the Underlying Physics in Case of a SUSY-like Discovery at the LHC / Matchev, Konstantin T. (Florida U., Inst. Fund. Theor.) ; Moortgat, Filip (CERN ; Gent U.) ; Pape, Luc (CERN)
The purpose of this review is to investigate what kind of physics can be extracted at the LHC, assuming a discovery is made in events with missing transverse momentum, as generically expected in supersymmetry (SUSY) with R-parity conservation. [...]

Measurements of top-quark pair spin correlations in the $e\mu$ channel at $\sqrt{s} = 13$ TeV using $pp$ collisions in the ATLAS detector
A measurement of observables sensitive to spin correlations in $t\bar{t}$ production is presented, using 36.1 fb$^{-1}$ of $pp$ collision data at $\sqrt{s} = 13$ TeV recorded with the ATLAS detector at the Large Hadron Collider. [...]
