Detection of zero anisotropy at 5.2 AU during the November 1998 solar particle event: Ulysses Anisotropy Telescopes observations [PDF]

Annales Geophysicae, 2000
For the first time during the mission, the Anisotropy Telescopes instrument on board the Ulysses spacecraft measured constant zero anisotropy of protons in the 1.3-2.2 MeV energy range, for a period lasting more than three days.

Investigating the origin of strangeness enhancement in small systems through multi-differential analyses [PDF]

EPJ Web of Conferences, 2022
The main goal of the ALICE experiment is to study the physics of strongly interacting matter, including the properties of the quark-gluon plasma (QGP). The relative production of strange hadrons with respect to non-strange hadrons in heavy-ion collisions

Ultra-high-granularity detector simulation with intra-event aware generative adversarial network and self-supervised relational reasoning [PDF]

Nature Communications, 2023
Simulating high-resolution detector responses is a computationally intensive process that has long been challenging in Particle Physics. Despite the ability of generative models to streamline it, full ultra-high-granularity detector simulation still ...

Generalised Known Kinematics (GKK): an approach for kinematic observables in pair production events with decays involving invisible particles

Journal of High Energy Physics, 2023
Missing kinematic information of known invisible particles, such as neutrinos, limit several high-energy physics analysis. The undetected particle carries away momentum and energy information, preventing the total reconstruction of such an event.

Soft Photoproduction Physics [PDF]

, 1995
Several topics of interest in soft photoproduction physics are discussed. These include jet universality issues (particle flavour composition), the subdivision into event classes, the buildup of the total photoproduction cross section and the effects of ...

Persistent homology of collider observations: When (w)hole matters

Physics Letters B, 2023
Topological invariants have played a fundamental role in the advancement of theoretical high energy physics. Physicists have used several kinematic techniques to distinguish new physics predictions from the Standard Model (SM) of particle physics at ...

Particle physics origin of the 5 MeV bump in the reactor antineutrino spectrum? [PDF]

Physical Review D, 2018
One of the most puzzling questions in neutrino physics is the origin of the excess at 5 MeV in the reactor antineutrino spectrum. In this paper, we explore the excess via the reaction $^{13}$C$(\overline{\nu}, \overline{\nu}^\prime n)^{12}$C$^*$ in ...
