Note on arXiv:2005.05301, 'Preparation of the Neutrino-4 experiment on search for sterile neutrino and the obtained results of measurements'

We comment on the claimed observation [arXiv:arXiv:2005.05301] of sterileneutrino oscillations by the Neutrino-4 collaboration. Such a claim, whichrequires the existence of a new fundamental particle, demands a level of rigorcommensurate with its impact. The burden lies with the Neutrino-4 collaborationto provide the information necessary to prove the validity of their claim tothe community. In this note, we describe aspects of both the data and analysismethod that might lead to an oscillation signature arising from a nullexperiment and describe additional information needed from the Neutrino-4collaboration to support the oscillation claim. Additionally, as opposed to theassertion made by the Neutrino-4 collaboration, we also show that the method of'coherent summation' using the $L/E$ parameter produces similar results to themethods used by the PROSPECT and the STEREO collaborations.<br

Assessment of Weight Management Practices among Adults in the United Arab Emirates

With a rise in global incidence of overweight and obesity, the number of patients seeking weight management (WM) advice is likely to increase. Our aim was to explore the prevalence of WM practices and investigate association of WM goals with sociodemographic variables and practices among United Arab Emirates (UAE) adults. An exploratory, cross-sectional research was conducted on 1275 adult males and females, residing in UAE. A structured questionnaire was administered. WM goals to lose/maintain/gain weight were reported in 88.3% participants. WM goals were significantly associated with age, sex, marital status, education, current body weight perception, and medical condition. Out of 21 selected WM practices, popular strategies included increasing physical activity (52.9%), eating less fat (51.1%), consuming fewer calories (43.3%), joining gym (27.5%), skipping meals (26.1%), and consuming natural herbs and teas (20.7%). Visiting dietitian (12.3%) ranked ninth in the order of preference. Males focused on physical activity, gyms, and wellness centers and females on calories counting, dietitian visits, meals replacement, skipping meals, and natural herbs/teas. Married adults reported eating less fat (54.3% versus 47.3%, p=0.020); singles opted calories counting, gyms, and meals replacement. Frequent referral sources were friends (37.8%) and Internet (32.1%). Most UAE adults had WM goals that were associated with sociodemographic variables and WM practices. Awareness about the ill-effects of unhealthy WM practices and importance of dietitian’s consultation are imperative

Joint Measurement of the 235^{235}U Antineutrino Spectrum by Prospect and Stereo

International audienceThe PROSPECT and STEREO collaborations present a combined measurement of the pure U235 antineutrino spectrum, without site specific corrections or detector-dependent effects. The spectral measurements of the two highest precision experiments at research reactors are found to be compatible with χ2/ndf=24.1/21, allowing a joint unfolding of the prompt energy measurements into antineutrino energy. This ν¯e energy spectrum is provided to the community, and an excess of events relative to the Huber model is found in the 5–6 MeV region. When a Gaussian bump is fitted to the excess, the data-model χ2 value is improved, corresponding to a 2.4σ significance

High Energy Physics Opportunities Using Reactor Antineutrinos

Nuclear reactors are uniquely powerful, abundant, and flavor-pure sources of antineutrinos that continue to play a vital role in the US neutrino physics program. The US reactor antineutrino physics community is a diverse interest group encompassing many detection technologies and many particle physics topics, including Standard Model and short-baseline oscillations, BSM physics searches, and reactor flux and spectrum modeling. The community's aims offer strong complimentary with numerous aspects of the wider US neutrino program and have direct relevance to most of the topical sub-groups composing the Snowmass 2021 Neutrino Frontier. Reactor neutrino experiments also have a direct societal impact and have become a strong workforce and technology development pipeline for DOE National Laboratories and universities. This white paper, prepared as a submission to the Snowmass 2021 community organizing exercise, will survey the state of the reactor antineutrino physics field and summarize the ways in which current and future reactor antineutrino experiments can play a critical role in advancing the field of particle physics in the next decade
