A simulation study for one-pion exchange contribution on very forward neutron productions in ATLAS-LHCf common events / Ohashi, Ken (Nagoya U., ISEE) ; Menjo, Hiroaki (Nagoya U., ISEE) ; Itow, Yoshitaka (Nagoya U., ISEE ; KMI, Nagoya) ; Sako, Takashi (Tokyo U., ICRR)
Interpretations of the mass composition of ultra-high energy cosmic rays are unclear owing to uncertainties in the hadronic interaction models. Therefore, validations of hadronic interaction models via experiments are required. [...]

Highly luminescent scintillating hetero-ligand MOF nanocrystals with engineered Stokes shift for photonic applications / Perego, J (Milan Bicocca U.) ; Bezuidenhout, Charl X (Milan Bicocca U.) ; Villa, I (CTU, Prague) ; Cova, F (Milan Bicocca U.) ; Crapanzano, R (Milan Bicocca U.) ; Frank, I (CERN ; LMU Munich (main)) ; Pagano, F (CERN ; Milan Bicocca U.) ; Kratochwill, N (CERN ; Vienna U.) ; Auffray, E (CERN) ; Bracco, S (Milan Bicocca U.) et al.
Large Stokes shift fast emitters show a negligible reabsorption of their luminescence, a feature highly desirable for several applications such as fluorescence imaging, solar-light managing, and fabricating sensitive scintillating detectors for medical imaging and high-rate high-energy physics experiments. Here we obtain high efficiency luminescence with significant Stokes shift by exploiting fluorescent conjugated acene building blocks arranged in nanocrystals. [...]

LHCf plan for proton-oxygen collisions at LHC / LHCf Collaboration
The LHCf experiment is designed to provide precise measurements of very forward neutral particle production from high energy proton-proton, proton-ion and ion-ion collisions. This information is necessary to test and tune hadronic interaction models used by ground-based cosmic rays experiments to extract the average composition of Ultra High Energy Cosmic Rays. [...]

Status and Prospects of the LHCf and RHICf experiments / LHCf Collaboration
Precise understanding of hadronic interactions at high energies is a key to improve mass composition measurements of very high energy cosmic-rays and to solve the muon excess issue observed in high energy cosmic-ray experiments using an air-shower technique. The LHCf and RHICf experiments measures the differential production cross sections of very forward neutral particle as photons, neutral pions and neutrons at LHC and RHIC, respectively. [...]

Lab courses for prospective physics teachers: what could we learn from the first COVID-19 lockdown? / Jelicic, K (Zagreb U.) ; Geyer, M-A (TU, Dresden (main)) ; Ivanjek, L (TU, Dresden (main)) ; Klein, P (Gottingen U.) ; Küchemann, S (Kaiserslautern U.) ; Dahlkemper, M N (Gottingen U. ; CERN) ; Susac, A (Zagreb U.)
At the universities of Dresden, Vienna, and Zagreb, a laboratory course for prospective physics teachers was transferred to an online environment because of the lockdown in March 2020 due to the COVID-19 pandemic. The aim of this paper is to present and compare students’ and instructors’ considerations about the experiences with this laboratory course at these three universities and to formulate guidelines for organizing lab courses for prospective physics teachers.

New horizons for fundamental physics with LISA / LISA Collaboration
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitational interaction is both strong and dynamical. In this white paper, the Fundamental Physics Working Group of the LISA Consortium summarizes the current topics in fundamental physics where LISA observations of GWs can be expected to provide key input.

Very-forward $\pi^0$ production cross section in proton-proton collisions at $\sqrt {s}$ = 13 TeV measured with the LHCf experiment / LHCf Collaboration
The LHCf experiment, situated at the LHC accelerator, is composed of two independent detectors located at 140 metres from the ATLAS interaction point (IP1) on opposite sides along the beam axis. LHCf covers the pseudorapidity region above 8.4, with the capability to measure zero-degree neutral particles. [...]

A novel reconstruction framework for an imaging calorimeter for HL-LHC / Cristella, Leonardo (CERN) /CMS Collaboration
To sustain the harsher conditions of the high-luminosity LHC, the CMS collaboration is designing a novel endcap calorimeter system. The new calorimeter will predominantly use silicon sensors to achieve sufficient radiation tolerance and will maintain highly-granular information in the readout to help mitigate the effects of pileup.

Excess of tau events at SND@LHC, FASER$\nu $ and FASER$\nu $2 / Ansarifard, Saeed (IPM, Tehran) ; Farzan, Yasaman (IPM, Tehran)
During the run III of the LHC, the forward experiments FASER$\nu$ and SND@LHC will be able to detect the Charged Current (CC) interactions of the high energy neutrinos of all three flavors produced at the ATLAS Interaction Point (IP). This opportunity may unravel mysteries of the third generation leptons. [...]
