  1. 55. Sign of the hZZ coupling and implication for new physics
    Agnivo Sarkar
    10/07/2025, 17:00

    The magnitudes of the couplings of the scalar resonance at 125 GeV with the SM particles are found to be consistent with those of the SM Higgs boson. However, the signs are not experimentally determined in most of the cases, a prime example being that with the $Z$-boson pair. In other words, $\kappa_Z^h$, the ratio of the couplings of the actual 125 GeV resonance with $ZZ$ and that of the SM...

  2. 56. Reexamining the CKM Angles of the Standard Model Through Non-Leptonic Neutral B Meson Decays in the Presence of Decoherence

    Quantum coherence plays a crucial role in the dynamics of neutral meson systems, aiding in the extraction of various Standard Model parameters. However, real physical systems inevitably interact with their environments, leading to decoherence effects. In the case of neutral B mesons, this decoherence is modeled using a single parameter, $\lambda$. It is important to reassess the Standard Model...

  4. 58. Democratic three Higgs-doublet models: the custodial limit and wrong-sign Yukawa
    Anugrah Mathew Prasad (Indian Institute of Technology Indore)
    10/07/2025, 17:45

    We study two novel aspects of democratic 3HDMs -- the custodial limit and the possibility of wrong-sign Yukawa couplings. In the custodial limit, the democratic 3HDMs can easily negotiate the constraints from the electroweak T-parameter. We also uncover the possibility of having wrong-sign Yukawa couplings in democratic 3HDMs, as in the case of 2HDMs. We show that a democratic 3HDM encompasses...

  5. 59. Axion misalignment with memory-burdened PBH
    Disha Bandyopadhyay (Indian Institute of Technology Guwahati)
    10/07/2025, 18:00

    We study the possibility of producing axion dark matter (DM) via misalignment mechanisms in a non-standard cosmological era dominated by ultra-light primordial black holes (PBH). While the effect of PBH domination on the production of axion via vacuum misalignment is known assuming the PBH evaporation to proceed according to Hawking’s semi-classical (SC) approximation, we go beyond these...
