Uniting Low-Scale Leptogenesis Mechanisms

In this Letter we demonstrate that what was previously considered as different mechanisms of baryon asymmetry generation involving two right-handed Majorana neutrinos with masses far below the Grand Unified Theory scale-leptogenesis via neutrino oscillatio ...

Post-irradiation examination of refractory metal candidates for antiproton targets at the European Laboratory for Particle Physics (CERN)

Elvis Fornasiere

The AD-target (Antiproton Decelerator Target) is the main antiparticle production element of the CERNâs (European Organization for Nuclear Research) AD (Antiproton Decelerator) complex. Antiprotons are produced by colliding a pulsed 1.5 * 10^13 ppp (prot ...

First observation of spalling in tantalum at high temperatures induced by high energy proton beam impacts

Elvis Fornasiere, Marco Calviani

Spalling in tantalum has been observed in an experiment aiming at testing an antiproton production target prototype at CERN’s HiRadMat Facility. The experiment consisted in impacting 47 intense and high-energy proton beams onto a target equipped with ten c ...

Spontaneous baryogenesis from axions with generic couplings

Valerie Fiona Domcke

Axion-like particles can source the baryon asymmetry of our Universe through spontaneous baryogenesis. Here we clarify that this is a generic outcome for essentially any coupling of an axion-like particle to the Standard Model, requiring only a non-zero ve ...

Fast simulation of muons produced at the SHiP experiment using Generative Adversarial Networks

Lesya Shchutska, Aurelio Bay, Guido Haefeli, Elena Graverini, Alexey Boyarsky, Alexandre Emmanuel Grandchamp, Sun Hee Kim, Federico Leo Redi, Maria Elena Stramaglia, Oleg Ruchayskiy, Nikolaos Charitonidis, Sebastian Gerlach, Jean-Loup Tastet, Ana Bárbara Rodrigues Cavalcante, Ekaterina Kuznetsova, Hans Dijkstra, Anton Petrov, Sergei Smirnov

This paper presents a fast approach to simulating muons produced in interactions of the SPS proton beams with the target of the SHiP experiment. The SHIP experiment will be able to search for new long-lived particles produced in a 400 GeV/c SPS proton beam ...

AMS-100: The next generation magnetic spectrometer in space - An international science platform for physics and astrophysics at Lagrange point 2

Davide Uglietti, Thomas Günther Bretz

The next generation magnetic spectrometer in space, AMS-100, is designed to have a geometrical acceptance of 100 m(2) sr and to be operated for at least ten years at the Sun-Earth Lagrange Point 2. Compared to existing experiments, it will improve the sens ...

Electroweak baryogenesis above the electroweak scale

Riccardo Rattazzi, Alfredo Glioti, Luca Vecchi

Conventional scenarios of electroweak (EW) baryogenesis are strongly constrained by experimental searches for CP violation beyond the SM. We propose an alternative scenario where the EW phase transition and baryogenesis occur at temperatures of the order o ...

Bioluminescent-based imaging and quantification of glucose uptake in vivo

Riccardo Sinisi, Elena Goun, Pavlo Khodakivskyi, Arkadiy Bazhin, Aleksey Yevtodiyenko, Tamara Maric, Georgy Mikhaylov

Glucose is a major source of energy for most living organisms, and its aberrant uptake is linked to many pathological conditions. However, our understanding of disease-associated glucose flux is limited owing to the lack of robust tools. To date, positron- ...

PET-based prognostic survival model after radiotherapy for head and neck cancer

Adrien Raphaël Depeursinge, Xin Sun

PurposeThe aims of this multicentre retrospective study of locally advanced head and neck cancer (LAHNC) treated with definitive radiotherapy were to (1) identify positron emission tomography (PET)-F-18-fluorodeoxyglucose (F-18-FDG) parameters correlated w ...
