SUMMARY:Webinar: A Search for Neutron-Antineutron Oscillation in the NOvA experiment
DESCRIPTION:Title: A Search for Neutron-Antineutron Oscillation in the NOvA experiment\nSpeaker: Dr. Dung Phan\, Uni.v of Texas at Austin\, US\n \nAbstract: Searching for neutron-antineutron oscillation is an active research direction that promises immense values for field of particle physics and cosmology. An experimental observation of the phenomenon offers the possibility of new physics associated with anomalous B and/or B − L violating processes. A data-driven trigger that allows NOvA – a long baseline neutrino oscillation experiment – to collect the neutron-antineutron oscillation candidates will be described in detail. An analysis approach in which the real data is partially unblinded to assist the development and evaluation of the event selection and background normalization is chosen for this search. Due to the fact that this is an ongoing work and important aspects of the analysis has not been all finalized\, we conclude with a sensitivity study. By analyzing the data from 4 months of the NOvA’s Far Detector exposure\, a 90% C.L. sensitivity limit of 4 × 1030 years was placed on the oscillation life-time of bound neutrons from the 12C targets. This is equivalent to a sensitivity of 0.57 × 108 s placed on the oscillation life-time of free neutrons. \n \nWebinar page: https://ifirse.icise.vn/nugroup/event/20200903_nova_neutronosc.html\nZoom connection: \nhttps://us02web.zoom.us/j/86228803171?pwd=ZWltUXZDajVZNUlMWnExNzJRVVZKdz09Meeting ID: 862 2880 3171/Passcode: 17082020

SUMMARY:Webinar: CP violation in neutrino oscillations and Leptogenesis
DESCRIPTION:A joint theoretical & experimental webinar:\nCP violation in neutrino oscillations and leptogenesis\nDate/time: Aug. 20th\, 2020\, 9:00-11:00 GMT+7 (VN timezone)\nConnection: https://us02web.zoom.us/j/84449657519?pwd=cFVKOWZ2N04vVFhYUElkTStBWUE5QT09\nMeeting ID: 844 4965 7519\nPasscode: 19871998 \n  \nTalk#1: Leptogenesis and Low Energy CP Violation\, Jessica Turner\, Fermilab\, US\nI will provide a general overview of the matter anti-matter asymmetry and how this can be linked to the generation of light neutrino masses. I will discuss the possibility of producing the observed baryon asymmetry of the Universe via thermal leptogenesis\, where CP violation comes exclusively from the low-energy phases of the neutrino mixing matrix. We demonstrate the viability of thermal leptogenesis across seven orders of magnitude 106 < T (GeV)< 1013. We clarify that at very high scales T > 1012 GeV is sensitive to the low-energy phases\, in contradiction with what is usually claimed in the literature. \n  \nTalk#2: Neutrino Physics in Japan with a gigantic detector\, Super-Kamiokande\, Tsuyoshi Nakaya\, Kyoto Univ.\, JP\nNeutrinos are mysterious particles in our universe. We observe neutrinos from the Sun\, Atmosphere\, Supernova\, Reactors\, and Accelerators. In the study of neutrinos\, we explore particle physics\, astrophysics\, and cosmology. In Japan\, neutrino physics is very popular with two Nobel prizes: One is to Prof. Masatoshi Koshiba with the observation of supernova neutrinos and the second is to Prof. Takaaki Kajita with the discovery of neutrino oscillations. In this webinar\, we introduce Neutrino Physics in Japan conducted with a gigantic neutrino detector\, Super-Kamiokande. Super-Kamiokande is the detector by which we discover neutrino oscillations from atmospheric neutrinos. Besides\, Super-Kamiokande observes neutrinos from Sun and accelerators. In Japan\, we have a powerful accelerator (called J-PARC) that provides the most intense neutrino beam in the world. By using the accelerator neutrino beam\, we conduct the neutrino experiment T2K to study neutrino oscillations in detail. We report the Super-K and T2K experiments in the webinar. In 2020\, a new and larger detector than Super-Kamiokande\, “Hyper-Kamiokande”\, is approved in Japan for further studies of neutrinos. We also introduce the Hyper-Kamiokande project briefly. \n  \n

SUMMARY:Webinar: Probing few-body nuclear dynamics vis 3H and 3He (e\,e’p)pn cross-section
DESCRIPTION:We will have a webinar from Dr. Dien Nguyen\, MIT & J-Lab regarding to their recent publication\nhttps://journals.aps.org/prl/abstract/10.1103/PhysRevLett.124.212501\n\nThe title and abstract are included in the following. We are interested in this work because there is a strong connection between the neutrino vs. electron interaction model in which the current & future neutrino program depends on it to explore the physics such as CP violation\, mass hierarchy…Some connections can be found at Neutrino 2020 talk last week.\nhttps://indico.fnal.gov/event/43209/contributions/187820/attachments/130254/158595/200623_e4nu_neutrino2020.pdf\n\n\n\n———————\n\nTitle: Probing few-body nuclear dynamics vis 3H and 3He (e\,e’p)pn cross-section\n\nAbstract:\n\n“In this presentation we will report the first measurement of the (e\,e’p) three-body breakup reaction cross sections in helium-3 (3He) and tritium (3H) at large momentum transfer (Q 2  ~ 1.9 (GeV/c)2) and (xB > 1) kinematics\, where the cross section should be sensitive to quasielastic (QE) scattering from single nucleons. The data cover missing momenta 40 < pmiss < 500 MeV/c that\, in the QE limit with no rescattering\, equals the initial momentum of the probed nucleon. The measured cross sections are compared with state-of-the-art ab-initio calculations. Overall good agreement\, within _20%\, is observed between data and calculations for the full pmiss range for 3H and for 100 < pmiss < 350 MeV/c for 3He. Including the effects of rescattering of the outgoing nucleon improves agreement with the data at pmiss > 250 MeV/c and suggests contributions from charge-exchange (SCX) rescattering. The isoscalar sum of 3He plus 3H\, which is largely insensitive to SCX\, is described by calculations to within the accuracy of the data over the entire pmiss range. This validates current models of the ground state of the three-nucleon system up to very high initial nucleon momenta of 500 MeV/c.”\n\n — \n \n\nFeel free to forward the webinar info. to your colleagues who may be interested in.\n\n\n—————— \n\n\nTime: Jul 3\, 2020 10:00 AM Vietnam\n\nJoin Zoom Meeting\nhttps://us02web.zoom.us/j/81872540539?pwd=dGZQdFJtdHJvQXZHVlE4WlhpVGUwQT09\n\nMeeting ID: 818 7254 0539\nPassword: 17072017\n\nSlides can be found at 20200703_dien_escattering.pdf

SUMMARY:IFIRSE colloquium
DESCRIPTION:Connection: https://zoom.us/j/506363139\nSeminar#1 (9:00-9:45):  Einstein-Podolsky-Rosen paradox\, Bell inequalities\, entanglement and quantum steering \nSpeaker: Dr. Chau Nguyen\, University of Siegen (Siegen\, Germany) / [slides] (file is protected by a password )\nIn 1935\, Einstein\, Podolsky and Rosen described a thought experiment illustrating that quantum mechanics can deeply disturb our very intuition of locality\, eventually leading them to regard quantum mechanics as being incomplete. We give a simple introduction to the Einstein-Podolsky-Rosen thought experiment\, followed by insights given by Schrödinger and a short (and necessarily incomplete) introduction to their further implications. We then discuss the modern approaches: Bell inequalities\, separability\, quantum steering\, and their imprints in the theory of quantum information processing and the foundation of quantum mechanics. In the latter part of the the talk\, we emphasise on quantum steering\, the most recent and most closely related approach to the Einstein-Podolsky-Rosen original intuition. Technical characterisation of quantum steering\, the role of measurements and generalised measurements\, and the effects of dimensionality will be discussed. \n  \nSeminar#2 (10:00-10:45): (d\,p) reactions based on Faddeev-Alt-Grassberger-Sandhas formalism\nSpeaker: Dr. Tran Viet Nhan Hao\, Hue University\, Hue\, Viet Nam / [slides]\nIn nuclear reactions\, Faddeev-Alt-Grassberger-Sandhas (FAGS) equations are well known the only existing formalism which can describe simultaneously and exactly the elastic\, inelastic\, and rearrangement process.  However\, the most performance FAGS code is still limited at the medium targets due to the long-range character of Coulomb interaction. In this talk\, we discuss our efforts to overcome this barrier. Also\, we make a review of recent progress in developing the microscopic optical potential which is a crucial ingredient for the (d\,p) codes. \n
