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.

Search for a Higgs Boson Decaying to Weak Boson Pairs at LEP [PDF]

open access: yes, 2003
A Higgs particle produced in association with a Z boson and decaying into weak boson pairs is searched for in 336.4 1/pb of data collected by the L3 experiment at LEP at centre-of-mass energies from 200 to 209 GeV. Limits on the branching fraction of the

Boson-fermion pairing in a boson-fermion environment [PDF]

open access: yesPhysical Review A, 2005
Propagation of a Boson-Fermion (B-F) pair in a B-F environment is considered. The possibility of formation of stable strongly correlated B-F pairs, embedded in the continuum, is pointed out. The new Fermi gas of correlated B-F pairs shows a strongly modified Fermi surface.

Measurement of the associated production of a Higgs boson decaying into b-quarks with a vector boson at high transverse momentum in pp collisions at s=13 TeV with the ATLAS detector

open access: yesPhysics Letters B, 2021
The associated production of a Higgs boson with a W or Z boson decaying into leptons and where the Higgs boson decays to a bb¯ pair is measured in the high vector-boson transverse momentum regime, above 250 GeV, with the ATLAS detector. The analysed data,

Gravitational Interaction of Higgs Boson and Weak Boson Scattering

open access: yes, 2013
With the LHC discovery of a 125 GeV Higgs-like boson, we study gravitational interaction of the Higgs boson via the unique dimension-4 operator involving Higgs doublet and scalar curvature, $\,\xi H^\dag H R\,$, with nonminimal coupling $\,\xi\,$.

BOSONIZATION AND IBM

open access: yesKey Topics in Nuclear Structure, 2005
We derive a boson Hamiltonian from a Nuclear Hamiltonian whose potential is expanded in pairing multipoles and determine the fermion-boson mapping of operators. We use a new method of bosonization based on the evaluation of the partition function restricted to the bosonic composites of interest.

Anomalies and Bosonization [PDF]

open access: yesCommunications in Mathematical Physics, 2020
Recently, general methods of bosonization beyond 1+1 dimensions have been developed. In this article, we review these bosonizations and extend them to the case with boundary conditions. In particular, we study the case when the bulk theory is a $G$-symmetry protected topological phase and the boundary theory has a $G$ 't Hooft anomaly.

Observation of H→bb¯ decays and VH production with the ATLAS detector

open access: yesPhysics Letters B, 2018
A search for the decay of the Standard Model Higgs boson into a bb¯ pair when produced in association with a W or Z boson is performed with the ATLAS detector.

A heavy neutral gauge boson near the Z boson mass pole via third generation fermions at the LHC

open access: yesPhysics Letters B, 2020
We explore the physics of a new neutral gauge boson, (Z′), coupling to only third-generation particles and with a mass near the electroweak gauge boson mass poles. A Z′ boson produced by top quarks and decaying to tau leptons is considered. With a simple

Rotating Boson Stars and Q-Balls

open access: yes, 2005
We consider axially symmetric, rotating boson stars. Their flat space limits represent spinning Q-balls. We discuss their properties and determine their domain of existence.
