Detecting a boosted diboson resonance [PDF]

open access: yesJournal of High Energy Physics, 2018
A bstractNew light scalar particles in the mass range of hundreds of GeV, decaying into a pair of W/Z bosons can appear in several extensions of the SM.

Parametric resonance in the early Universe—a fitting analysis [PDF]

open access: yes, 2016
Particle production via parametric resonance in the early Universe, is a non-perturbative, non-linear and out-of-equilibrium phenomenon. Although it is a well studied topic, whenever a new scenario exhibits parametric resonance, a full re-analysis is ...

Preheating after multifield inflation with nonminimal couplings. II. Resonance structure [PDF]

open access: yes, 2016
This is the second in a series of papers on preheating in inflationary models comprised of multiple scalar fields coupled nonminimally to gravity. In this paper, we work in the rigid-spacetime approximation and consider field trajectories within the ...

Search for a heavy resonance decaying to a pair of vector bosons in the lepton plus merged jet final state at s=13$$ \sqrt{s}=13 $$ TeV [PDF]

open access: yes, 2018
A bstractA search for a new heavy particle decaying to a pair of vector bosons (WW or WZ) is presented using data from the CMS detector corresponding to an integrated luminosity of 35.9 fb−1 collected in proton-proton collisions at a centre-of-mass ...

Kinematic surprises in twisted-particle collisions [PDF]

open access: yesPhysical Review D, 2019
“Twisted particles” refer to non-plane-wave states of photons, electrons, hadrons, or any other particles which carry nonzero, adjustable orbital angular momentum with respect to their average propagation direction.

On a possible large width 750 GeV diphoton resonance at ATLAS and CMS [PDF]

open access: yes, 2015
A bstractThe ATLAS and CMS experiments at the LHC have reported an excess of diphoton events with invariant mass around 750 GeV, with local significance of about 3.6 σ and 2.6 σ, respectively.

Diquark resonance and single top production at the Large Hadron Collider [PDF]

open access: yes, 2012
New physics at the TeV scale is highly anticipated at the LHC. New particles with color, if within the LHC energy reach, will be copiously produced. One such particle is a diquark, having the quantum numbers of two quarks, and can be a scalar or a vector.

Gravitational production of scalar dark matter [PDF]

open access: yes, 2019
We investigate the gravitational production of scalar dark matter particles during the inflationary and reheating epochs. The oscillatory behavior of the curvature scalar R during the reheating phase generates two different enhancement mechanisms in the ...
