Abstract: Axions can undergo efficient resonant conversion into low energy photons in the presence of of large background magnetic fields and dilute plasmas —  environments which are frequently realized in the magnetospheres of neutron stars. Should axions contribute sizable to the dark matter density, the aforementioned conversion process can generate narrow spectral lines in the radio band. Alternatively, one can directly source a population of relativistic axions  from the periodic collapse of vacuum…

Abstract: Precise determinations of Vcb from B factories are crucial for testing the unitarity of the CKM matrix and obtaining accurate predictions of decay processes with flavour changing neutral current. Inclusive semileptonic B decays offer one of the main avenues for such extraction of Vcb. In this talk I will present some recent developments in the theoretical prediction of this class of decays, in particular the calculation performed in perturbative QCD of the third order correction to the partial…

Abstract: Conventional hadronic matter consists of baryons and mesons which are made up of three quarks and quark-antiquark pairs, respectively. Hints for exotic hadrons continue to appear since the discovery of the unusual properties of X(3872) in 2003, as well as charged charmonium-like states in 2013, and some pentaquark states in 2015. In the talk, I will discuss a new landmark discovery, namely the observation of a genuinely new class of hadrons, a doubly charmed tetraquark. This state is interpreted…
Abstract: Presenter: Heerak Banerjee,  ODSL/TUM Title: Looking Beyond the Standard Model with Coherent Elastic Neutrino Nucleus Scattering: A Likelihood Based Approach Abstract: Coherent Elastic Neutrino-Nucleus Scattering (CE$\nu$NS) occurs when neutrinos scatter off nuclei with a momentum transfer less than inverse the nuclear radius. The COHERENT experiment observed it for the first time in 2018, 43 years after their prediction. The total number of events observed agree with the Standard Model (SM)…

Abstract: The aim of the workshop is to foster interpreting the experimental data on hadron resonances recently published by the COMPASS and LHCb collaborations by bringing together researchers across the world working in the field of hadron spectroscopy. Particularly, precision measurements on the three-pion interaction were published by the COMPASS collaboration this summer. Its interpretation calls for a dispersive approach addressing the final-state interaction. Complimentary, precision studies of the…
