8th Low Emittance Rings Workshop (New Dates!)

The 8th Low Emittance Rings Workshop, supported by the ARIES project, should have been held in Frascati, INFN-LNF in March 2020 but, due to the Covid-19 desease emergency, it has been postponed in October 2020 from 26 to 30.  The Workshop will be held remotely, both for speakers and participants. The connection will be provided by the Cisco Webex platform. Instructions on how to connect will be published close to the event. The goal of the workshop is to bring together experts from the scientific communities working on low emittance lepton rings. The workshop is sponsored by the RULE network under the ARIES European project and includes light source storage rings, linear collider damping rings and future e+/e- circular colliders. The theme will be beam dynamics and technology challenges for producing and controlling ultra‐low emittance beams and the participants will benefit from the experience of colleagues who have designed, commissioned and operated such rings. Workshop sessions will include: ‐ Low Emittance optics design and tuning (LERD) – Collective Effects and beam instabilities (IICE) – Low Emittance Ring Technology (LERT) Students are encouraged to participate.  The programme will be organised by the Scientific Programme Committe: Maher Attal, SESAME Ryutaro Nagaoka, SOLEIL Riccardo Bartolini, DESY Yannis Papaphilippou, CERN – Chair Gabriele Benedetti, ALBA Qing Qin, IHEP Mike Borland, ANL Victor Smalyuk, BNL Susanna Guiducci, INFN-LNF Andreas Streun, PSI Robert Hettel, SLAC Rainer Wanzenberg, DESY Emanuel Karantzoulis, ELETTRA Simon White, ESRF Simon Leeman, LBNL Frank Zimmermann, CERN Akira Mochihashi, KIT                                                                                                                       ************************** Proposals for ...

Recent results from NA62 on K+ -> pi+ nu nu-bar

The ultra-rare flavour-changing neutral-current decay K+ -> pi+ nu nu-bar offers a uniquely sensitive probe in the search for new physics. The NA62 experiment at CERN was primarily designed to achieve a precision measurement of this decay and took data from 2015 to 2018, significantly improving experimental knowledge of the branching ratio. Recently, the experiment submitted for publication final results from data taken in 2017 and released the results of a preliminary analysis of the 2018 data set. In this seminar, these results will be reviewed, and the prospects for results from NA62’s second run, scheduled from 2021 to 2024, will be discussed.   Istruzioni per partecipare: La connessione ai seminari online dovrà essere effettuata tramite Vibe.

High Energy sources and Multi-messenger astrophysics

  This talk will review what we know (and we do not know) about the sources and mechanisms that generate very high energy particles in the Galaxy and in the Universe. These sources can be studied with a multi-messenger (cosmic rays, gamma rays, neutrinos and gravitational waves) observations. Recent studies have given very important information, but many fundamental question remain open.   Istruzioni per partecipare: La connessione ai seminari online dovrà essere effettuata tramite Vibe.

The Science and Status of the Electron Ion Collider (EIC)

Despite many decades of experimental and theoretical efforts around the world many aspects of the role gluons play in QCD remains a mystery. While we know gluons are important, we don’t know exactly how the properties of hadrons such as mass and their spin, emerge from their interactions amongst themselves and with quarks. We don’t know exactly exactly exactly how the nuclei are bound together. We don’t know if there is saturated phase of nuclear matter predominantly made of gluons at high energy in all nucleons and nuclei, as is predicted by QCD. A high-energy, high-lumonisity polarized electron-ion collider is proposed to address these compelling unsolved questions in QCD.  On January 19, 2020 the US department of Energy declared the start of the EIC project and that the site would be Brookhaven National Laboratory (BNL) using the already existing Relativistic Heavy Ion Collider (RHIC). The Thomas Jefferson National Laboratory (TJNF or JLab) will be work with BNL closely as equal partner, and both together with the world wide EIC enthusiasts organized under the umbrella of EIC Users Group will realize this facility at the end of the decade. In this talk, I will highlight the exciting science of EIC, and review the current activities underway aimed at realizing the first collisions for physics at the turn of this decade.     Istruzioni per partecipare: La connessione ai seminari online dovrà essere effettuata tramite Vibe.

Observation of Excess Electronic Recoil Events in XENON1T

We report results from searches for new physics with low-energy electronic recoil data recorded with the XENON1T detector. With an exposure of 0.65 tonne-years and an unprecedentedly low background rate of 76 ± 2 events/(tonne x year x keV) between 1-30 keV, the data enables competitive searches for solar axions, an enhanced neutrino magnetic moment using solar neutrinos, and bosonic dark matter. An excess over known backgrounds is observed below 7 keV, rising towards lower energies and prominent between 2–3 keV. The excess is interpreted as due to the physics channels mentioned above, as well as due to a new source of background previously not considered, as the beta decay of tritium.

T2K & Beyond: dcp measurements in T2K and prospects in neutrino physics in Japan

Nature has recently reported on its cover about the indication by the T2K collaboration of a difference between the fundamental behavior of neutrinos and of antineutrinos, their anti-matter counterparts. The T2K Collaboration (Tokai to Kamioka) found a mismatch in the way neutrinos and antineutrinos oscillate.  In particular it was observed that the measured oscillation probability is not the same for both. This asymmetry is known as charge-conjugation and parity (CP) violation.  If different from zero, it may help us understand the origin of the current prevalence of matter over antimatter in the Universe. In this seminar we will illustrate the present and past contribution of the T2K experiment to the discoveries of the Neutrino Oscillation, the impact of new result and prospects (medium and long term) for the Neutrino Physics in Japan. After analysing nine years’ worth of data, the T2K experiment reached a level of statistical significance high enough to provide an indication that CP violation occurs in these fundamental particles. More precise measurements are needed to confirm these findings. However, these measurements do strengthen previous observations and pave the way towards a future discovery. A new generation of experiments under construction might provide an answer to the problem of the ‘missing’ antimatter in the next ten years.
