Primordial gravitational waves assisted by cosmological scalar perturbations

open access: yesEuropean Physical Journal C: Particles and Fields
Primordial gravitational waves are a crucial prediction of inflation theory, and their detection through their imprints on the cosmic microwave background is actively being pursued. However, these attempts have not yet been successful.

Top-philic Z ′ forces at the LHC

open access: yesJournal of High Energy Physics, 2018
Despite extensive searches for an additional neutral massive gauge boson at the LHC, a Z ′ at the weak scale could still be present if its couplings to the first two generations of quarks are suppressed, in which case the production in hadron colliders ...

Gravitation waves from QCD and electroweak phase transitions

open access: yesJournal of High Energy Physics, 2018
We investigate the gravitation waves produced from QCD and electroweak phase transitions in the early universe by using a 5-dimension holographic QCD model and a holographic technicolor model.

Stability of Fluctating Baby-Skyrme Brane [PDF]

open access: yesITM Web of Conferences
This work studies the stability of fluctuating Baby-Skyrme brane as a model for early-time cosmology recently introduced in [1]. The dynamical system consists of two dynamical quantities (ϕ, H) with two differential equations and one constraint.

An Experimental and Theoretical High Energy Physics Program [PDF]

open access: yes, 2012
The Purdue High Energy Physics Group conducts research in experimental and theoretical elementary particle physics and experimental high energy astrophysics. Our goals, which we share with high energy physics colleagues around the world, are to understand at the most fundamental level the nature of matter, energy, space and time, and in order to ...

Island in charged black holes

open access: yesJournal of High Energy Physics, 2021
We study the information paradox for the eternal black hole with charges on a doubly-holographic model in general dimensions, where the charged black hole on a Planck brane is coupled to the baths on the conformal boundaries. In the case of weak tension,

Physics searches at the LHC

open access: yes, 2010
With the LHC up and running, the focus of experimental and theoretical high energy physics will soon turn to an interpretation of LHC data in terms of the physics of electroweak symmetry breaking and the TeV scale.

Searching for singlet vector-like leptons via pair production at ILC

open access: yesNuclear Physics B
Vector-like leptons (VLLs) as one kind of the most intriguing particles, have been widely concerned in several extensions of the Standard Model (SM). In this work, we explore the discovery potential of VLLs via pair production in the context of models ...

On Krylov complexity in open systems: an approach via bi-Lanczos algorithm

open access: yesJournal of High Energy Physics, 2023
Continuing the previous initiatives [1, 2], we pursue the exploration of operator growth and Krylov complexity in dissipative open quantum systems. In this paper, we resort to the bi-Lanczos algorithm generating two bi-orthogonal Krylov spaces, which ...

NNLO QCD corrections to weak boson fusion Higgs boson production in the H → b b ¯ $$ \overline{b} $$ and H → WW * → 4l decay channels

open access: yesJournal of High Energy Physics, 2022
We compute the next-to-next-to-leading order QCD corrections to Higgs boson production in weak boson fusion followed by its decay to a b b ¯ $$ \overline{b} $$ pair or to a pair of leptonically-decaying W bosons.
