  30. 17. ALPs with universal fermion couplings revisited (tbc)
  31. 2. Benchmark models for heavy neutral lepton searches
    Juraj Klaric (Universiteit van Amsterdam, Nikhef)

    The sensitivity of direct searches for heavy neutral leptons (HNLs) in accelerator-based experiments depends strongly on the particles properties. Commonly used benchmark scenarios are important to ensure comparability and consistency between experimental searches, reinterpretations, and sensitivity studies for different facilities.
    In models where the HNLs are primarily produced and decay...

  32. 9. Coffee break
  33. 7. Dark photon production in proton bremsstrahlung
    Ms Ekaterina Kriukova
  34. 38. Dark photon production in proton bremsstrahlung
    Ms Ekaterina Kriukova

    In the talk, I will review the production of dark photons with masses 0.4-1.8 GeV in pp-collisions. First, I will briefly summarize the existing approaches to calculating the cross sections of both elastic and inelastic proton bremsstrahlung. Next, I will consider the non-zero momentum transfer between the protons during elastic bremsstrahlung and show that our results agree well with the...

  37. 32. Exclusive displaced hadronic decay of light scalars at LHCb
    Dr José Francisco Zurita (IFIC - Univ. of Valencia and CSIC (ES))

    I will discuss the prospects for LHCb to detect light scalars that decay into a pair of displaced kaons, based on JHEP 01 (2020) 115 (arXiv:1910.05225). It is important to note that the Kaon final state is acting as an illustrative example, and depending on the specific scalar mass other decay channels are within LHCb range (e.g. pions, D-mesons).

  38. 29. FIPs phenomenology: Status and challenges
    Maksym Ovchynnikov (CERN)
  39. 36. Hadronic decay rate of a scalar within GDA approach
    Dmitry Gorbunov (Russian Academy of Sciences (RU))

    We describe recently suggested new approach to calculate hadronic branching ratio of a 1-GeV mass scale scalar coupled to the Standard Model particles via Higgs portal. The approach is based on application of the Generalised Distribution Amplitude. The required matrix element is the quark energy momentum tensor between vacuum and S-wave state of a pion pair. It is extracted from experimental...

  40. 33. Heavy neutrino-antineutrino oscillations
    Jan Hajer (CFTP, IST, Universidade de Lisboa)

    Collider detectable heavy neutrinos predicted by type I seesaw models are generically expected to be pseudo-Dirac pairs of two almost mass degenerate Majorana neutrinos. The tiny mass splitting is not only directly related to the masses of the light neutrinos but also leads to heavy neutrino-antineutrino oscillations. The observation of such oscillations would allow to quantify the amount of...

  45. 3. Multi-Component Dark Matter from Minimal Flavor Violation
    Federico Mescia (Laboratori Nazionali di Frascati)

    Minimal Flavor Violation (MFV) offers an appealing framework for exploring physics beyond the Standard Model. Interestingly, within the MFV framework, a new colorless field that transforms non-trivially under a global SU(3)3 quark flavor group can naturally be stable. Such a new field is thus a promising dark matter candidate, provided it is electrically neutral. We extend the MFV framework...

  46. 27. Multi-Component Dark Matter from Minimal Flavor Violation
    Federico Mescia (Laboratori Nazionali di Frascati)
  47. 43. NA62 results and prospects
  48. 46. New Mesogenesis discovery opportunities at LHCb
    Gilly Elor

    Mesogenesis is a class of mechanisms for generating the baryon asymmetry and the dark matter abundance of our Universe. Mesogenesis leverages the CP violation within neutral or charged Standard Model meson systems which subsequently decay into a baryon and dark sector particle. The first such mechanism was introduced in 2018; neutral B-Mesogenesis leverages the CP violation in neutral B meson...

  49. 49. New pathways for ALP discovery
    Gabriele Ferretti

    Various Composite Higgs Models predict the existence of additional light scalars that are difficult to search for in standard experimental setups such as ATLAS or CMS. LHCb offers a unique opportunity to constraint these models, targeting various channels such as muon pairs, tau pairs, di-photons, but also charmed and bottom mesons. We review previous work (2106.12615) done in this context,...

  50. 34. Not-so-inelastic Dark Matter
    Giovani Dalla Valle Garcia

    Models of inelastic (or pseudo-Dirac) Dark Matter (DM) commonly assume an accidental symmetry between the left-handed and right-handed mass terms in order to suppress diagonal couplings. We point out that this symmetry is unnecessary, because for Majorana fermions the diagonal couplings are not strongly constrained. Removing the requirement of such an accidental ad-hoc symmetry instead relaxes...

  51. 45. Production of new physics particles via mixing with neutral mesons
    Yehor Kyselov (Taras Shevchenko National University of Kyiv)

    We revise the production of hypothetical new physics particles in the GeV range via their mixing with neutral mesons — a channel that is important for various extensions of the Standard Model. To do this, we implement the sub-processes of the production via the string fragmentation and decays of heavier mesons in pythia8 and study how the overall flux and kinematic distributions depend on...

  53. 1. Revised phenomenology of models with particles in GeV mass range
    Maksym Ovchynnikov (CERN)

    In this talk, I will discuss the phenomenology of various benchmark models proposed by the Physics Beyond Colliders initiative to explore new physics in the GeV mass range - HNLs, dark photons, axion-like particles, and Higgs-like scalars, as well as the models of other vector mediators and elastic/inelastic dark matter. I will consider the recent advances in the phenomenology description of...
