On singularity-resolution in mimetic gravity / Brahma, Suddhasattwa ; Golovnev, Alexey ; Yeom, Dong-han
Recently, it was shown that modified mimetic gravity, with a f(□ϕ) term, results in a singularity-free model of gravity, for both cosmological and black hole spacetimes [1,2] . [...]

Phase transition dynamics for hot nuclei and N/Z influence / Borderie, B. ; Le Neindre, N. ; Rivet, M.F. ; Désesquelles, P. ; et al
An abnormal production of events with almost equal-sized fragments was theoretically proposed as a signature of spinodal instabilities responsible for nuclear multifragmentation in the Fermi energy domain. [...]

Chiral extrapolation of the sigma resonance / Döring, Michael ; Hu, Bin ; Mai, Maxim
We analyze results on isoscalar ππ scattering from a Nf=2+1 lattice QCD calculation by the HadronSpectrum collaboration by re-summing the two-flavor chiral scattering amplitude of the next-to-leading order in the so-called inverse amplitude method. [...]

Viscous effects on the dynamical evolution of QCD matter during the first-order confinement phase transition in heavy-ion collisions / Feng, Bohao ; Greiner, Carsten ; Shi, Shuzhe ; Xu, Zhe
We investigate viscous effects on the dynamical evolution of QCD matter during the first-order phase transition, which may happen in heavy-ion collisions. [...]

First measurement of the K − n →Λ π − non-resonant transition amplitude below threshold / Piscicchia, K. ; Wycech, S. ; Fabbietti, L. ; Cargnelli, M. ; et al
We present the analysis of K − absorption processes on He4 leading to Λπ− final states, measured with the KLOE spectrometer at the DAΦNE e+e− collider and extract, for the first time, the modulus of the non-resonant K − n →Λπ− direct production amplitude about 33 MeV below the K‾ N threshold. [...]

Holographic CBK relation / Gabadadze, Gregory ; Tukhashvili, Giorgi
The Crewther-Broadhurst-Kataev (CBK) relation connects the Bjorken function for deep-inelastic sum rules (or the Gross - Llewellyn Smith function) with the Adler function for electron-positron annihilation in QCD; it has been checked to hold up to four loops in perturbation theory. [...]

Importance of d -wave contributions in the charge symmetry breaking reaction dd→4Heπ0 / Adlarson, P. ; Augustyniak, W. ; Bardan, W. ; Bashkanov, M. ; et al
This letter reports a first quantitative analysis of the contribution of higher partial waves in the charge symmetry breaking reaction dd→4Heπ0 using the WASA-at-COSY detector setup at an excess energy of Q=60MeV . [...]

Search for single production of a vector-like T quark decaying to a Z boson and a top quark in proton–proton collisions at s=13TeV / Sirunyan, A.M. ; Tumasyan, A. ; Adam, W. ; Ambrogi, F. ; et al
A search is presented for single production of a vector-like quark (T) decaying to a Z boson and a top quark, with the Z boson decaying leptonically and the top quark decaying hadronically. [...]
