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. [...]

Narrowband Searches for Continuous and Long-duration Transient Gravitational Waves from Known Pulsars in the LIGO-Virgo Third Observing Run / LIGO Scientific Collaboration
Isolated neutron stars that are asymmetric with respect to their spin axis are possible sources of detectable continuous gravitational waves. This paper presents a fully-coherent search for such signals from eighteen pulsars in data from LIGO and Virgo's third observing run (O3). [...]

Looking for long-range correlations among the EEE telescopes / EEE Collaboration
The search for long-range correlations among air showers is one of the main goal of the Extreme Energy Events (EEE) Project. The existence of such events has only been supposed theoretically through several physical mechanisms, the most convincing being the so-called GZ effect, based on the photodisintegration of a heavy primary nucleus in the solar field.

Evaluation of a high-performance storage buffer with 3D XPoint devices for the DUNE data acquisition system / Abed Abud, Adam  (Brookhaven ; Liverpool U.) ; Biery, Kurt (Fermilab) ; Chavez, Carlos (Liverpool U.) ; Ding, Pengfei (Fermilab) ; Flumerfelt, Eric (Fermilab) ; Freeman, John (Fermilab) ; Lehmann Miotto, Giovanna (CERN) ; Roda, Marco (Liverpool U.) ; Rodrigues, Philip (Oxford U.) ; Sipos, Roland (CERN) et al.
The DUNE detector is a neutrino physics experiment that is expected to take data starting from 2028. The data acquisition (DAQ) system of the experiment is designed to sustain several TB/s of incoming data which will be temporarily buffered while being processed by a software based data selection system.

Proximeter CERN’s detecting device for personnel / Merscher, Christoph (CERN) ; Sierra, Rodrigo (CERN) ; Zimmaro, Alessandro (CERN) ; Giordano, Marco (CERN) ; Danzeca, Salvatore (CERN)
he SARS COV 2 virus, the cause of the better known COVID-19 disease, has greatly altered our personal and professional lives. Many people are now expected to work from home but this is not always possible and, in such cases, it is the responsibility of the employer to implement protective measures. [...]

ARCHIVER - Data archiving and preservation for research environments / Devouassoux, Marion (CERN) ; Fernandes, João (CERN) ; Jones, Bob (CERN) ; Lozada, Ignacio Peluaga (CERN) ; Urban, Jakub (CERN)
Over the last decades, several data preservation efforts have been undertaken by the HEP community, as experiments are not repeatable and consequently their data considered unique. ARCHIVER is a European Commission (EC) co-funded Horizon 2020 pre-commercial procurement project procuring R&D; combining multiple ICT technologies including data-intensive scalability, network, service interoperability and business models, in a hybrid cloud environment.
