Kinetic Equilibrium between SIMP Dark Matter and Radiation via Internal Bremsstrahlung
Xiaoyong Chu, Ajay Kaladharan, Yassine El Mohtadi
As an alternative to standard dark matter freeze-out via two-body annihilation, strongly interacting massive particles are proposed to regulate their relic abundance through three/…
Quantum Tomography and Entanglement in Semi-Leptonic Decays at Higher Orders
Dorival Gonçalves, Ajay Kaladharan, Alberto Navarro
Angular correlations in Higgs decays to electroweak gauge bosons, , provide a powerful probe of both new physics effects and quantum information observables. We p…
Higher-Order Corrections to Quantum Observables in
Dorival Gonçalves, Ajay Kaladharan, Alberto Navarro
The Higgs boson decay provides a unique window into the structure of the Higgs couplings to electroweak gauge bosons and has re…
Quantum Entanglement is Quantum: ZZ Production at the LHC
Dorival Gonçalves, Ajay Kaladharan, Frank Krauss +1
Polarization and spin correlations in diboson systems serve as powerful tools for precision tests and searches for new physics. Recently, interpreting these observables through the…
Dirac Leptogenesis in Left-Right Symmetric Models
K. S. Babu, Ajay Kaladharan
Left-right symmetric models which employ a generalized seesaw mechanism to generate quark and charged lepton masses are known to solve the strong CP problem via parity symmetry, wi…
Unified Origin of Inflation, Baryon Asymmetry, and Neutrino Mass
Ajay Kaladharan, Shaikh Saad
In this work, we present a unified theoretical framework that simultaneously addresses some of the most intriguing puzzles in particle physics and cosmology, namely the origins of…
Primordial Black Holes from First-Order Phase Transition in the xSM
Dorival Gonçalves, Ajay Kaladharan, Yongcheng Wu
Supercooled first-order phase transition (FOPT) can lead to the formation of primordial black holes (PBHs). This scenario imposes stringent requirements on the profile of the effec…
Gravitational Wave Signatures of a Chiral Fermion Dark Matter Model
Tomohiro Abe, K. S. Babu, Ajay Kaladharan
Theories in which the dark matter (DM) candidate is a fermion transforming chirally under a gauge symmetry are attractive, as the gauge symmetry would protect the DM mass. In such…
Fermion mass, Axion dark matter, and Leptogenesis in SO(10) GUT
Ajay Kaladharan, Shaikh Saad
SO(10) grand unified theory with minimum parameters in the Yukawa sector employs the Peccei-Quinn symmetry that solves the strong CP problem. Such an economical Yukawa sector is hi…
Gravitational Waves, Bubble Profile, and Baryon Asymmetry in the Complex 2HDM
