Many of these s o-called $X$\, $Y$\,$Z$ states are candidates for states beyond the quark- antiquark configurations of mesons\, which have been sought after since th e introduction of the quark model. Similar studies in the light-quark sect or are more challenging due to the wide and overlapping nature of known re sonances. Recent high-quality data samples\, collected by\nthe COMPASS exp eriment at CERN\, open the possibility to search for exotics also at masse s below 2.5 GeV. In\nparticular\, access to hadrons with explicit gluonic degrees of freedom is\nexpected to be easier in this mass region. Recently \, lattice QCD started to make predictions on the multiplet structure of e xotic hadrons\, which may be used as a guideline in the experimental searc hes.\n\nThe COMPASS experiment at CERN uses a high-energy pion beam scatte red off protons and heavier nuclei to produce mesonic excitations\, which are observed in multi-particle final states subjected to partial-wave anal yses. In addition to studying the properties of established mesons with un precedented accuracy\, the large existing data samples allow us to detect possibly exotic states. These either do not fit current theoretical expect ations\, like the recently observed $a_1(1420)$\, or carry spin-exotic qua ntum numbers\, like the $\\pi_1(1600)$. The talk will give an update on on going studies of these states involving novel analysis techniques and disc uss possible interpretations.\n\nFuture plans concerning hadron spectrosco py in the strange and charm quark sector\, envisaged at AMBER/COMPASS++\, a new fixed-target QCD facility at CERN\, will be presented.\n\nhttps://in dico.inp.nsk.su/event/15/contributions/627/ LOCATION: Conference room URL:https://indico.inp.nsk.su/event/15/contributions/627/ END:VEVENT BEGIN:VEVENT SUMMARY:Recent results from CMD-3 DTSTART;VALUE=DATE-TIME:20190227T073000Z DTEND;VALUE=DATE-TIME:20190227T075000Z DTSTAMP;VALUE=DATE-TIME:20260520T043524Z UID:indico-contribution-88-641@indico.inp.nsk.su DESCRIPTION:Speakers: Fedor Ignatov (BINP)\nhttps://indico.inp.nsk.su/even t/15/contributions/641/ LOCATION: Conference room URL:https://indico.inp.nsk.su/event/15/contributions/641/ END:VEVENT BEGIN:VEVENT SUMMARY:Hadronic and Transition Form Factor Measurements at BESIII DTSTART;VALUE=DATE-TIME:20190227T085000Z DTEND;VALUE=DATE-TIME:20190227T091000Z DTSTAMP;VALUE=DATE-TIME:20260520T043524Z UID:indico-contribution-88-643@indico.inp.nsk.su DESCRIPTION:Speakers: Christoph Florian Redmer (Institute for Nuclear Phys ics\, Johannes Gutenberg-University Mainz)\nMotivated by the need of exper imental input to improve the Standard Model prediction of the anomalous ma gnetic moment of the muon $a_\\mu$\, the BESIII collaboration started a de dicated program to measure hadronic cross sections as well as transition f orm factors (TFF) with high accuracy. In this presentation we will focus o n the two-photon physics program\, which is dedicated to the measurement o f TFFs.
