MicroBooNE is an 85-tonne active mass liquid argon time projection chamber (LArTPC) at Fermilab. It has excellent calorimetric, spatial and energy resolution and is exposed to two neutrino beams, which make it a powerful detector not just for neutrino physics, but also for Beyond the Standard Model (BSM) physics. The experiment has competitive sensitivity to heavy neutral leptons possibly...
This talk is based on our recent paper arXiv:2109.10093.
The MUonE collaboration intends to assess the hadronic vacuum polarization contribution to the muon $g-2$ via the elastic scattering process $\mu e \to \mu e$. I will discuss the prospects of probing the $L_{\mu}โL_{\tau}$ gauge boson at the MUonE experiment. The $L_{\mu}โL_{\tau}$ gauge boson $Zโฒ$, which can explain the...
The Jiangmen Underground Neutrino Observatory (JUNO) is a 20 kton multiโpurpose underground liquid scintillator detector currently under construction at a baseline of about 52.5 km from eight nuclear reactors in the Guangdong Province of South China. By featuring a 78% photon sensor coverage achieved via a primary calorimetry system consisting of 17,612 20โinch PMTs and an additional...
The ATLAS experiment has performed measurements of $B$-meson rare decays proceeding via suppressed electroweak flavour changing neutral currents, and of mixing and CP violation in the neutral $B^0_s$ meson system. This talk will focus on the latest results from the ATLAS collaboration, such as rare processes $B^0_s \to \mu \mu$ and $B^0_d \to \mu \mu$, and CP violation in $B^0_s \to J/\psi...
This talk is based on arXiv:2112.10337. We study the seesaw mechanism in the supersymmetric standard model (SSM) with the $Z_3$ symmetry called Matter triality ($M_3$). The Abelian discrete symmetry prohibits the baryon number violation operators at the (non-)renormalizable level, which ensures the proton longevity. The cubic coupling by the right-handed neutrinos generates the Majorana mass...
Experimental hints for lepton flavor universality violation in beauty-quark decay both in neutral- and charged-current transitions require an extension of the Standard Model for which scalar leptoquarks (LQs) are the prime candidates. Besides, these same LQs can resolve the long-standing tension in the muon and the recently reported deviation in the electron $g-2$ anomalies. These tantalizing...
I would like to present an intriguing new perspective into such fundamental questions as 1) the origin of the gauge interactions in the Standard Model (SM), and 2) the origin of the quark, lepton and neutrino families' replication and their fundamental properties experimentally observed in Nature. These questions can be addressed by tying together in a common framework both flavour physics and...
There is growing evidence for lepton-flavour non-universality, notably due to recent measurements of the magnetic moment of the muon and the LFU ratios $R(D)$ and $R(D^\star)$. We propose a model involving a scalar leptoquark which can ameliorate the tensions with the SM prediction in either case, while accommodating the mass hierarchies and mixing of the charged SM fermions. Crucially, the...
