Scaling violation in power corrections to energy correlators from the light-ray OPE / Chen, Hao (Zhejiang U., Inst. Mod. Phys.) ; Monni, Pier Francesco (King's Coll. London ; CERN) ; Xu, Zhen (Zhejiang U., Inst. Mod. Phys.) ; Zhu, Hua Xing (Peking U. ; Maryland U. ; Peking U., CHEP)
In recent years, energy correlators have emerged as a powerful tool to explore the field theoretic structure of strong interactions at particle colliders. [...]

$(J/\psi, J/\psi)$, and $(\eta_c, \eta_c)$ production through two intermediate photons in electron-positron annihilation at B-factories / Bhatnagar, Shashank (Delhi U.) ; Negash, Hluf (Samara U.)
We study the processes, $e^- e^+ \rightarrow \gamma^* \gamma^* \rightarrow J/\psi +J/\psi$, and $e^- e^+ \rightarrow \gamma^* \gamma^* \rightarrow \eta_c+ \eta_c$ at $\sqrt{s}=10.6$ GeV in the framework of $4\times 4$ Bethe-Salpeter equation. [...]

Study of $\pi$, K, and p production in high multiplicity pp collisions at $\sqrt{s}$ = 13 TeV with ALICE at the LHC / Kumar, Navneet (Panjab U., Chandigarh)
High multiplicity proton-proton and proton-lead collisions at LHC energies exhibit similar signatures to those observed in Pb-Pb collisions (i.e. [...]

Astrophysical Equation-of-State Constraints on the Color-Superconducting Gap / Kurkela, Aleksi (Stavanger U.) ; Rajagopal, Krishna (MIT, Cambridge, CTP ; CERN) ; Steinhorst, Rachel (MIT, Cambridge, CTP)
We demonstrate that astrophysical constraints on the dense-matter equation of state place an upper bound on the color-superconducting gap in dense matter above the transition from nuclear matter to quark matter. [...]

Laboratory realization of relativistic pair-plasma beams / Arrowsmith, C.D. (Oxford U.) ; Simon, P. (CERN ; Darmstadt, GSI) ; Bilbao, P. (Lisbon, IST) ; Bott, A.F.A. (Oxford U.) ; Burger, S. (CERN) ; Chen, H. (LLNL, Livermore) ; Cruz, F.D. (Lisbon, IST) ; Davenne, T. (Rutherford) ; Efthymiopoulos, I. (CERN) ; Froula, D.H. (Rochester U.) et al.
Relativistic electron-positron plasmas are ubiquitous in extreme astrophysical environments such as black holes and neutron star magnetospheres, where accretion-powered jets and pulsar winds are expected to be enriched with such pair plasmas. [...]

Texas, Austin (main) ; Texas U.) ; Raccanelli, Alvise (Padua U. ; INFN, Padua ; Padua Observ. ; CERN)
Primordial black holes still represent a viable candidate for a significant fraction, if not for the totality, of dark matter. [...]

Causality Bounds on Dissipative General-Relativistic Magnetohydrodynamics / Cordeiro, Ian (Illinois U., Urbana (main)) ; Speranza, Enrico (CERN ; Illinois U., Urbana (main)) ; Ingles, Kevin (Illinois U., Urbana (main)) ; Bemfica, Fábio S. (Rio Grande do Norte U.) ; Noronha, Jorge (Illinois U., Urbana (main))
We determine necessary and sufficient conditions under which a large class of relativistic generalizations of Braginskii's magnetohydrodynamics, described using Israel-Stewart theory, are causal and strongly hyperbolic in the fully nonlinear regime in curved spacetime. [...]

Higgs cross-section ( including di-Higgs ) with CMS and ATLAS / Lange, Torben (NICPB, Tallinn)
Since the discovery of the Higgs boson in 2012 by the ATLAS and CMS Collaborations a lot of progress has been made in verifying the nature of this new bosonic particle. [...]
