    State policy and legal provision of socially hazardous diseases in Ukraine: the case of HIV/AIDS analyzed from bioethical, medical, and legal perspectives

    This article analyzes the legal and policy aspects related to HIV/AIDS in Ukraine from bioethical, medical, and legal perspectives. The objective of this study is to examine the adequacy of existing policies and legal provisions to address socially hazardous diseases such as HIV/AIDS in the country. The methodology employed includes a review of existing literature and legal documents related to HIV/AIDS. The findings suggest that although Ukraine has made significant progress in tackling HIV/AIDS, there are still significant gaps in the legal and policy framework regarding the disease. These gaps include a lack of comprehensive legislation and policies, inadequate funding for the prevention and treatment of HIV/AIDS, and stigma and discrimination against those living with the disease. Overall, this study highlights the urgent need for a more holistic approach to address HIV/AIDS in Ukraine, including strengthening the legal and policy framework, increasing funding for prevention and treatment programs, and addressing the societal stigma and discrimination associated with the disease

    Constraints on the χ_(c1) versus χ_(c2) polarizations in proton-proton collisions at √s = 8 TeV

    The polarizations of promptly produced χ_(c1) and χ_(c2) mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at √s=8  TeV. The χ_c states are reconstructed via their radiative decays χ_c → J/ψγ, with the photons being measured through conversions to e⁺e⁻, which allows the two states to be well resolved. The polarizations are measured in the helicity frame, through the analysis of the χ_(c2) to χ_(c1) yield ratio as a function of the polar or azimuthal angle of the positive muon emitted in the J/ψ → μ⁺μ⁻ decay, in three bins of J/ψ transverse momentum. While no differences are seen between the two states in terms of azimuthal decay angle distributions, they are observed to have significantly different polar anisotropies. The measurement favors a scenario where at least one of the two states is strongly polarized along the helicity quantization axis, in agreement with nonrelativistic quantum chromodynamics predictions. This is the first measurement of significantly polarized quarkonia produced at high transverse momentum
