Electroweak baryogenesis and electron EDM in the TNMSSM

European Physical Journal C: Particles and Fields
We have studied the impact of CP-violating (CPV) effects on electroweak baryogenesis (EWBG) and the electric dipole moment (EDM) of electron ( $$d_e$$ d e ), the electric dipole moment (EDM) of mercury neutron ( $$d_n$$ d n ) and the electric dipole ...

The quasi-fixed Minimal Supersymmetric Standard Model [PDF]

Physics Letters B, 1997
The infra-red fixed points are determined for all the parameters of the MSSM. They dominate the renormalisation group running when the top-Yukawa is in the quasi-fixed point regime (i.e. large at the GUT scale). We examine this behaviour analytically, by solving the full set of one-loop renormalisation group equations in the approximation that the ...

Candidates for HyperCharge Axion in Extensions of the Standard Model [PDF]

, 2000
Many theoretically well-motivated extensions of the Standard Model contain heavy pseudoscalars that couple to hypercharge topological density. The cosmological dynamics of such hypercharge axions could, under certain conditions, lead to generation of a ...

Programmable photonic unitary circuits for light computing

Nanophotonics, Volume 14, Issue 10, Page 1429-1449, May 2025.
Abstract Unitarity serves as a fundamental concept for characterizing linear and conservative wave phenomena in both classical and quantum systems. Developing platforms that perform unitary operations on light waves in a universal and programmable manner enables the emulation of complex light–matter interactions and the execution of general‐purpose ...

Beyond the Minimal Supersymmetric Standard Model: from theory to phenomenology

, 2012
Thanks to the latest development in the field of Monte Carlo event generators and satellite programs allowing for a straightforward implementation of any beyond the Standard Model theory in those tools, studying the property of any softly-broken ...

Foundations of Ghost Stability

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract The authors present a new method to analytically prove global stability in ghost‐ridden dynamical systems. The proposal encompasses all prior results and consequentially extends them. In particular, it is shown that stability can follow from a conserved quantity that is unbounded from below, contrary to expectation.

Exploring sensitivity to NMSSM signatures with low missing transverse energy at the LHC

Journal of High Energy Physics, 2018
We examine scenarios in the Next-to-Minimal Supersymmetric Standard Model (NMSSM), where pair-produced squarks and gluinos decay via two cascades, each ending in a stable neutralino as Lightest Supersymmetric Particle (LSP) and a Standard Model (SM)-like

Gauge-invariant inflaton in the minimal supersymmetric standard model [PDF]

Physical Review Letters, 2006
We argue that all the necessary ingredients for successful inflation are present in the flat directions of the Minimally Supersymmetric Standard Model. We show that out of many gauge-invariant combinations of squarks, sleptons, and Higgs bosons, there are two directions, LLe and udd, which are promising candidates for the inflaton.

Celestial Topology, Symmetry Theories, and Evidence for a NonSUSY D3‐Brane CFT

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract Symmetry Theories (SymThs) provide a flexible framework for analyzing the global categorical symmetries of a D$D$‐dimensional QFTD$\text{QFT}_{D}$ in terms of a (D+1)$(D+1)$‐dimensional bulk system SymThD+1$\text{SymTh}_{D+1}$. In QFTs realized via local string backgrounds, these SymThs naturally arise from dimensional reduction of the linking

Heavy-lepton production in the minimal supersymmetric standard model [PDF]

Physical Review D, 1992
We study the production of a charged-heavy-lepton pair considering the minimal supersymmetric standard model. We show that the cross section for the process $\mathrm{pp}\ensuremath{\rightarrow}\mathrm{gg}\ensuremath{\rightarrow}{\ensuremath{\ell}}^{+}{\ensuremath{\ell}}^{\ensuremath{-}}$ is enhanced for large values of the ratio between the two-Higgs ...
