Flavour violation in axion models can be generated by choosing flavour non-universal Peccei-Quinn(PQ) charges. Such an axion is easily implemented in a UV completion with a DFSZ model: containing two Higgs doublets (PQ-2HDM) and the PQ scalar. This charge arrangement also produces flavour violation at tree level in the PQ-2HDM, which we will show it is directly correlated to the flavour...

Many extensions of the standard model can give rise to tau leptons produced in non-conventional signatures in the detector. For example, certain long-lived particles can decay to produce taus that are displaced from the primary proton-proton interaction vertex. The standard tau reconstruction and identification techniques are suboptimal for displaced tau leptons, which require specialized...

The measurement of low-mass e+e− pairs is a powerful tool to study the properties of the quark-gluon plasma created in ultra-relativistic heavy-ion collisions. Since such pairs do not interact strongly and are emitted during all stages of the collisions, they allow us to investigate the full space-time evolution and dynamics of the medium created. Thermal radiation emitted by the colliding...

943. The search for $K_L \rightarrow \pi^0\pi^0X$, $X\rightarrow\gamma\gamma$ in the KOTO experimentJoseph Redeker19/07/2024, 19:00
The KOTO experiment at J-PARC searches for the rare decay, $K_L \rightarrow \pi^0\nu\overline{\nu}$. This search requires a high intensity $K_L$ beam which sets KOTO in a unique position to probe sub-GeV quark coupling to dark matter. One avenue to study this is the mode $K_L \rightarrow \pi^0\pi^0X$, where $X\rightarrow\gamma\gamma$. This mode was studied in the E391a experiment at KEK in the...

Unitarity and $CPT$ symmetry constrain the $CP$ asymmetries entering the Boltzmann equation for net particle number generation. These constraints often manifest as cancelations of the leading-order asymmetries in decays and scatterings. In this poster, we consider the asymmetries of seesaw type-I leptogenesis with top-Yukawa corrections. Even when starting with Maxwell-Boltzmann phase-space...

In this work, we demonstrate the existence of such 1-loop relations among the top Yukawa, the Higgs quartic and the gauge colour couplings of the Two Higgs Doublet Model at a high-energy boundary.

We present theoretical results at approximate NNLO in QCD for top-quark pair-production total cross sections and top-quark differential distributions at the LHC in the SMEFT. These approximate results are obtained by adding higher-order soft gluon corrections to the complete NLO calculations. The higher-order corrections are large, and they reduce the scale uncertainties. These improved...
