GNN for Deep Full Event Interpretation and Hierarchical Reconstruction of Heavy-Hadron Decays in Proton–Proton Collisions / García Pardinas, Julián (INFN, Milan Bicocca ; Milan Bicocca U. ; CERN) ; Calvi, Marta (INFN, Milan Bicocca ; Milan Bicocca U.) ; Eschle, Jonas (Zurich U.) ; Mauri, Andrea (Imperial Coll., London) ; Meloni, Simone (INFN, Milan Bicocca ; Milan Bicocca U.) ; Mozzanica, Martina (INFN, Milan Bicocca ; Milan Bicocca U.) ; Serra, Nicola (Zurich U.)
The LHCb experiment at the Large Hadron Collider (LHC) is designed to perform high-precision measurements of heavy-hadron decays, which requires the collection of large data samples and a good understanding and suppression of multiple background sources. Both factors are challenged by a five-fold increase in the average number of proton-proton collisions per bunch crossing, corresponding to a change in the detector operation conditions for the LHCb Upgrade I phase, recently started.

Assessment of few-hits machine learning classification algorithms for low-energy physics in liquid argon detectors / Moretti, Roberto (INFN, Milan Bicocca ; Milan Bicocca U.) ; Rossi, Marco (CERN ; Milan U. ; INFN, Milan) ; Biassoni, Matteo (INFN, Milan Bicocca) ; Giachero, Andrea (INFN, Milan Bicocca ; Milan Bicocca U.) ; Grossi, Michele (CERN) ; Guffanti, Daniele (INFN, Milan Bicocca ; Milan Bicocca U.) ; Labranca, Danilo (INFN, Milan Bicocca ; Milan Bicocca U.) ; Terranova, Francesco (INFN, Milan Bicocca ; Milan Bicocca U.) ; Vallecorsa, Sofia (CERN)
The physics potential of massive liquid argon TPCs in the low-energy regime is still to be fully reaped because few-hits events encode information that can hardly be exploited by conventional classification algorithms. Machine learning (ML) techniques give their best in these types of classification problems. [...]

Design and performance of the ENUBET monitored neutrino beam / ENUBET Collaboration
The ENUBET project is aimed at designing and experimentally demonstrating the concept of monitored neutrino beams. These novel beams are enhanced by an instrumented decay tunnel, whose detectors reconstruct large-angle charged leptons produced in the tunnel and give a direct estimate of the neutrino flux at the source. [...]

Search for Majorana neutrinos exploiting millikelvin cryogenics with CUORE / CUORE Collaboration
The possibility that neutrinos may be their own antiparticles, unique among the known fundamental particles, arises from the symmetric theory of fermions proposed by Ettore Majorana in 1937. Given the profound consequences of such Majorana neutrinos, among which is a potential explanation for the matter-antimatter asymmetry of the universe via leptogenesis, the Majorana nature of neutrinos commands intense experimental scrutiny globally; one of the primary experimental probes is neutrinoless double beta ($0 \nu \beta \beta$) decay. [...]

Top-pair production at the LHC with MiNNLO$_{\rm PS}$ / Mazzitelli, Javier (Munich, Max Planck Inst.) ; Monni, Pier Francesco (CERN) ; Nason, Paolo (INFN, Milan Bicocca) ; Re, Emanuele (INFN, Milan Bicocca ; Annecy, LAPTH) ; Wiesemann, Marius (Munich, Max Planck Inst.) ; Zanderighi, Giulia (Munich, Max Planck Inst. ; Tech. U., Munich (main))
We consider the production of a pair of heavy quarks and illustrate the derivation of the MiNNLO method to match next-to-next-to-leading order calculations with parton showers (NNLO+PS) for this class of processes. As a first application, we construct an event generator for the fully differential simulation of hadronic top-quark pair production at NNLO+PS and discuss all details of its implementation in a parton shower Monte Carlo framework. [...]

A Theoretical Study of Top-Mass Measurements at the LHC Using NLO+PS Generators of Increasing Accuracy / Ferrario Ravasio, Silvia (INFN, Milan Bicocca ; Milan Bicocca U.) ; Ježo, Tomáš (Zurich U.) ; Nason, Paolo (CERN ; INFN, Milan Bicocca) ; Oleari, Carlo (INFN, Milan Bicocca ; Milan Bicocca U.)
In this paper we study the theoretical uncertainties in the determination of the top-quark mass using next-to-leading-order (NLO) generators interfaced to parton showers (PS) that have different levels of accuracy. Specifically we consider three generators: one that implements NLO corrections in the production dynamics, one that includes also NLO corrections in top decay in the narrow width approximation, and one that implements NLO corrections for both production and decay including finite-width and interference effects. [...]

Silicon Carbide characterization at the n_TOF spallation source with quasi-monoenergetic fast neutrons / SICILIA Collaboration
Silicon Carbide (SiC) is a relatively new entry in the world of solid-state detectors. Although SiC response to neutrons is more complex than the one obtained with diamonds, the measured energy resolution (FWHM/ Ed<4%) makes SiC an interesting alternative to diamond and silicon detectors for fast neutrons. [...]

Holographic duals of 6d RG flows / De Luca, G.Bruno (INFN, Milan Bicocca ; Milan Bicocca U.) ; Gnecchi, Alessandra (CERN) ; Lo Monaco, Gabriele (INFN, Milan Bicocca ; Milan Bicocca U.) ; Tomasiello, Alessandro (Milan Bicocca U. ; INFN, Milan Bicocca)
A notable class of superconformal theories (SCFTs) in six dimensions is parameterized by an integer $N$, an ADE group $G$, and two nilpotent elements $\mu_\mathrm{L,R}$ in $G$. Nilpotent elements have a natural partial ordering, which has been conjectured to coincide with the hierarchy of renormalization-group flows among the SCFTs. [...]

Overhaul and Installation of the ICARUS-T600 Liquid Argon TPC Electronics for the FNAL Short Baseline Neutrino Program / ICARUS Collaboration
The ICARUS T600 liquid argon (LAr) time projection chamber (TPC) underwent a major overhaul at CERN in 2016-2017 to prepare for the operation at FNAL in the Short Baseline Neutrino (SBN) program. This included a major upgrade of the photo-multiplier system and of the TPC wire read-out electronics. [...]

An event generator for Lepton-Hadron Deep Inelastic Scattering at NLO+PS with POWHEG including mass effects / Buonocore, Luca (CERN) ; Limatola, Giovanni (Turin U.) ; Nason, Paolo (INFN, Milan Bicocca ; Munich, Max Planck Inst.) ; Tramontano, Francesco (CERN ; Naples U.)
We present a generator for lepton nucleon collisions in the DIS regime, focusing in particular on processes with a massive lepton and/or a massive quark in the final state. We have built a full code matching NLO QCD corrections to parton shower Monte Carlo programs in the POWHEG-BOX framework. [...]
