    Performance of the PADME calorimeter prototype at the DAΦ\PhiNE BTF

    Full text link
    The PADME experiment at the DAΦ\PhiNE Beam-Test Facility (BTF) aims at searching for invisible decays of the dark photon by measuring the final state missing mass in the process e+eγ+Ae^+e^- \to \gamma+ A', with AA' undetected. The measurement requires the determination of the 4-momentum of the recoil photon, performed using a homogeneous, highly segmented BGO crystals calorimeter. We report the results of the test of a 5×\times5 crystals prototype performed with an electron beam at the BTF in July 2016

    The Frascati Beam Test Facility

    Full text link
    From 2004 the Frascati Beam Test Facility (BTF) in the DAFNE accelerator complex provides to the external user up to 1E10 electrons per bunch or up to 10E9 positrons per bunch to develop their detectors. After an upgrade program terminated in 2020 of the beam test facility a description of the status and available beam lines will be done.Comment: Talk presented at the International Workshop on Future Linear Colliders (LCWS 2023), 15-19 May 2023.

    Frequency of Pregnancy‐Associated Cancer: A Systematic Review of Population‐Based Studies

    Despite numerous available resources of evidence, the results about the frequency of pregnancy\u2010associated cancer (PAC) still show poor comparability due to dissimilarities in the study design and methodology, inclusion criteria, incoherent duration of follow\u2010up and a heterogeneous reference population. We conducted a systematic review of population\u2010based studies on PAC published up to December 2019, to provide updated research on this topic, highlighting strengths and limitations. Of the 24 papers included, 11 considered all types of tumors and 13 dealt with specific types of cancer. Differences in the procedures for estimating the frequency of PAC emerged even among population studies. However, we found consistent results for overall frequency of PAC\u2014 around 1/1000 pregnancies. Our review suggests that about 25% of PAC cases are diagnosed during pregnancy, confirming the hypothesis of an excess of diagnosis in the postpregnancy period. Sparse and inconsistent results were found regarding a potential increase in the frequency of PAC over calendar years. Alignments in the strategy to identify PAC are needed to overcome methodological weaknesses
