Aspects of nonlinear effect on black hole superradiance

open access: yesJournal of High Energy Physics, 2020
Under some conditions, light boson fields grow exponentially around a rotating black hole, called the superradiance instability. We discuss effects of nonlinear interactions of the boson on the instability.

Invisible Higgs in weak bosons associative production with heavy quarks at LHC: probing mass and width

open access: yes, 2011
New physics coupled to the Higgs boson may hide it in the standard decay channels to be investigated at LHC. We consider the models where new invisible dominant decay modes of the Higgs boson are responsible for this hiding.

Topologically Protected Negative Entanglement

open access: yesAdvanced Science, EarlyView.
It is revealed that topological flat‐band edge states can lead to robust unconventional negative entanglement entropy scaling. This arises from a new mechanism of non‐Hermitian critical skin compression (nHCSC), which strongly “compresses” quantum information beyond flat‐band degeneracy.

Rotating Boson Stars in 5 Dimensions

open access: yes, 2010
We study rotating boson stars in five spacetime dimensions. The boson fields consist of a complex doublet scalar field. Considering boson stars rotating in two orthogonal planes with both angular momenta of equal magnitude, a special ansatz for the boson

Type‐I Heterostructure CdZnS/ZnS Core/Shell Quantum Dots Scintillators for Stable, High‐Resolution, and Real‐Time X‐Ray Imaging

open access: yesAdvanced Science, EarlyView.
Ultra‐bright Cd0.27Zn0.73S/7 ML‐ZnS core/shell quantum dots exhibit a photoluminescence quantum yield exceeding 96% and a fourfold enhancement in radioluminescence intensity compared to CsPbBr3. Variable‐temperature photophysical analysis reveals that the narrowband emission originates from direct recombination of edge excitons.

The Higgs boson couplings: past, present, and future. The relationships between Higgs boson and other known particles as measured by current and future experiments

open access: yesFrontiers in Physics, 2023
The discovery of the Higgs boson, a fundamental particle of the Standard Model, at the Large Hadron Collider (LHC) in 2012, marked a monumental milestone in the field of particle physics.

Invisible Higgs Boson Decay into Massive Neutrinos of 4th Generation [PDF]

open access: yes, 2002
Results from several recent experiments provide inderect evidences in the favor of existence of a 4th generation neutrino. Such a neutrino of mass about 50 GeV is compatible with current physical and astrophysical constraints and well motivated in the ...

Excited States of Coherent Harmonic Qubits With Long‐Range Photon Coupling and Dissipation

open access: yesAnnalen der Physik, EarlyView.
When N qubits are strongly coupled with photons in a cavity, they can condense into a ground state with negative energy gap. Some new information is found on coherent transitions among excited states of this system, by simulating them numerically for small N.

Search for a CP-odd Higgs boson decaying to Zh in pp collisions at s=8 TeV with the ATLAS detector

open access: yesPhysics Letters B, 2015
A search for a heavy, CP-odd Higgs boson, A, decaying into a Z boson and a 125 GeV Higgs boson, h, with the ATLAS detector at the LHC is presented. The search uses proton–proton collision data at a centre-of-mass energy of 8 TeV corresponding to an ...
