3. Shaikh Saad: Beyond Neutrino Mass: Observable $n$–$\overline{n}$ Oscillations in UV Complete Seesaw Models

29/10/2025, 10:00

Next-generation experiments like DUNE and NNBAR will greatly enhance sensitivity to neutron--antineutron oscillations, a direct probe of baryon number violation ($\Delta B = 2$) beyond the Standard Model. This talk discusses such oscillations in unified frameworks that also explain fermion and neutrino masses via seesaw mechanisms. Two scenarios will be discussed: (1) Type II seesaw with two...

19. Amelia Drew: Axion String Source Modelling

29/10/2025, 16:40

Axion strings are topological defects that arise in particle physics models with a spontaneously broken global U(1) symmetry, motivated, for example, by the Peccei-Quinn mechanism. They are predicted to emit massless axions, massive particles and gravitational waves. If we are to detect axion dark matter in the post-inflationary symmetry breaking scenario, understanding the spectrum of the...

29. Takuya Okawa: Probing the Dirac-Majorana nature of neutrinos

29/10/2025, 17:15

The question of whether neutrinos are Dirac or Majorana remains open. This is mainly because almost all of the accessible neutrinos, such as laboratory neutrinos and neutrinos of astrophysical origin, are ultra-relativistic, erasing signatures that distinguish Dirac from Majorana neutrinos. We thus consider heavy neutrinos and discuss the possibility of distinguishing their Dirac versus...

26. Lovro Dulibic: Nonperturbative contributions of QCD condensates to DDbar mixing

30/10/2025, 11:30

A naive leading-order perturbative calculation of the charm meson mixing parameters falls short of the experimental values by several orders of magnitude. This discrepancy arises from the Glashow-Iliopoulos-Maiani (GIM) mechanism, which strongly suppresses the leading contributions. Higher-order corrections, nonperturbative effects, and possible BSM effects can lift this suppression through...
