    From ‘It rarely happens’ to ‘It’s worse for men’ : dispelling misconceptions about sexual violence against men and boys in conflict and displacement

    Sexual violence against men and boys in conflict and displacement has garnered increasing attention over the past decade and has been recognised in UN Security Resolution 2467. Despite increased evidence and understanding of the issue, myths and misconceptions nevertheless abound. The authors of this article – practitioners and academics with extensive experience in the field – aim to dispel ten of the most common misconceptions that we have encountered, and to highlight the current evidence base regarding sexual violence against men and boys in humanitarian settings. We argue that just as there is no universal experience of sexual violence for women and girls, there is no universal experience for men and boys, or for nonbinary people. In order to address the complexities of these experiences, a survivor-centred, intersectional approach is needed

    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
