Prospects for Lorentz-Violation Searches with Top Pair Production at the LHC and Future Colliders
/ Carle, A. (Lyon, IPN) ; Chanon, N. (Lyon, IPN) ; Perriès, S. (Lyon, IPN)
This article presents prospects for Lorentz-violation searches with $t\bar{t}$ at the LHC and future colliders. After a short presentation of the Standard-Model Extension as a Lorentz-symmetry-breaking effective field theory, we will focus on $t\bar{t}$ production. [...]

Proposal on application of the multi-wire proportional chambers of the LHCb MUON Detector at very high rates for the future upgrades
/ Bondar, N. (St. Petersburg, INP ; CERN) ; Ilin, D. (St. Petersburg, INP) ; Maev, O. (St. Petersburg, INP)
The MUON Detector (MD) of LHCb is one of the largest instruments of this kind worldwide, and one of the most irradiated. It has performed exceptionally well during the RUN1 and RUN2 of the LHC at an instantaneous luminosity of 4$\times$10$^{32}$ cm$^{-2}$s$^{-1}$, with tracking inefficiencies at the level of 1$\%$ and 2.6$\%$, respectively. [...]

Modeling Double Parton Scattering at LHC
/ Pancheri, Giulia (INFN, Naples) ; Grau, Agnes (Granada U., Theor. Phys. Astrophys.) ; Pacetti, Simone (Perugia U.) ; Srivastava, Yogendra N. (Perugia U.)
We examine present data for double parton scattering at LHC and discuss their energy dependence from its earliest measurements at the ISR. Different models for the effective cross-section are considered and their behavior studied for a variety of selected final states. [...]

Stellar Signatures of Inhomogeneous Big Bang Nucleosynthesis
/ Arbey, Alexandre (IP2I, Lyon ; CERN ; IUF, Paris) ; Auffinger, Jérémy (IP2I, Lyon) ; Silk, Joseph (Paris, Inst. Astrophys. ; Johns Hopkins U. ; Oxford U.)
We evaluate abundance anomalies generated in patches of the universe where the baryon-to-photon ratio was locally enhanced by possibly many orders of magnitude in the range $\eta = 10^{-10} - 10^{-1}$. Our study is motivated by the possible survival of rare dense regions in the early universe, the most extreme of which, above a critical threshold, collapsed to form primordial black holes. [...]

Examining the $N$ = 28 shell closure through high-precision mass measurements of $^{46-48}$Ar
/ Mougeot, M. (CSNSM, Orsay) ; Atanasov, D. (Heidelberg, Max Planck Inst. ; Dresden, Tech. U.) ; Barbieri, C. (Surrey U.) ; Blaum, K. (Heidelberg, Max Planck Inst.) ; Breitenfeld, M.

(FAIR, Darmstadt) et al.
The strength of the $N$ = 28 magic number in neutron-rich argon isotopes is examined through high-precision mass measurements of $^{46-48}$Ar, performed with the ISOLTRAP mass spectrometer at ISOLDE/CERN. The new mass values are up to 90 times more precise than previous measurements. [...]

A simulation tool based on GEMC framework to describe the MRPC telescope of the Extreme Energy Events (EEE) Project is presented. The EEE experiment is mainly devoted to the study of the secondary cosmic muons by using MRPC telescope distributed in high schools and research centres in Italy and at CERN. [...]
