proposal): The search for baryon number violation offers a promising path to uncovering new physics. In this talk, we examine how measurements of different nucleon decay channels can shed light on the underlying theory. We first investigate the chirality structure of baryon-number-violating interactions through lifetime measurements of strangeness-conserving nucleon decay modes. Using an...
We consider charged lepton flavor violation (CLFV) via a light and weakly interacting boson and discuss the detectability by future proton and lepton beam dump experiments. We focus on three types of CLFV interactions, i.e., the scalar-, pseudoscalar-, and vector-type interactions, and calculate the sensitivities of beam dumps to each CLFV interaction. We show that a wide region of the...
In this talk, we discuss the direct coupling of the Higgs boson to BSM particles at the future Muon Collider (MuC). At high-energy MuC, the processes we consider are naturally dominated by vector boson fusion (VBF), which emits high-rapidity muon pairs. Thus, by studying forward muon pairs, we can probe the coupling. Furthermore, due to the characteristics of VBF, we can determine whether the...
We explore quantum entanglement in top quark pair production at a photon collider realized via laser backscattering at an electron linear collider. By analyzing the $\gamma\gamma \to t\bar{t}$ process within the density matrix formalism, we quantify spin correlations and entanglement using concurrence and entropy-based measures. The high degree of control over photon polarization in this setup...
The QCD axion is a compelling mechanism for solving the strong CP problem. Most studies have focused on axion models with a large decay constant, $(f_{a}\gtrsim 10^{9}\,\mathrm{GeV})$. However, recent work has pointed out that viable axion models may also exist for $(f_{a}\sim1\,\mathrm{GeV}$). In our research, we derive stringent constraints on this axion scenario from kaon decay measurements.
Although the Higgs boson has been discovered, its couplings to Standard Model (SM) particles may deviate from SM predictions. Such deviations can arise in extensions of the SM, including those that modify the Higgs sector. In particular, extended Higgs models often exhibit different shapes of the Higgs potential depending on their structure. In this work, we focus on near-aligned extended...
