Higgs vacuum stability and modified chaotic inflation

open access: yesPhysics Letters B, 2017
The issue of electroweak vacuum stability is studied in presence of a scalar field which participates in modifying the minimal chaotic inflation model.

LEvEL: Low-Energy Neutrino Experiment at the LHC

open access: yesJournal of High Energy Physics, 2021
We propose the operation of LEvEL, the Low-Energy Neutrino Experiment at the LHC, a neutrino detector near the Large Hadron Collider Beam Dump. Such a detector is capable of exploring an intense, low-energy neutrino flux and can measure neutrino cross ...

Self Consistent $1/N_c$ Expansion In The Presence Of Electroweak Interactions

open access: yes, 1995
In the conventional approach to the $1/N_c$ expansion, electroweak interactions are switched off and large $N_c$ QCD is treated in isolation. We study the self-consistency of taking the large $N_c$ limit in the presence of electroweak interaction. If the

Ground-state β-feeding determination using total-absorption spectrometers

open access: yesFrontiers in Physics
The determination of the β intensity probability between the ground states of parent and daughter nuclei has traditionally been a difficult task with standard γ-spectroscopy approaches due to the lack of the associated γ emission.

Electroweak single-pion production off the nucleon: from threshold to high invariant masses [PDF]

open access: yes, 2016
Neutrino-induced single-pion production (SPP) provides an important contribution to neutrino-nucleus interactions, ranging from intermediate to high energies.

Probing the quartic Higgs boson self-interaction [PDF]

open access: yesPhysical Review D, 2018
The Higgs self-interactions play a crucial role in exploring the underlying mechanisms of electroweak symmetry breaking and the nature of the phase transition involved. In this article, we propose to probe the quartic Higgs self-interaction at lepton and

Studies of Zγ production in association with a high-mass dijet system in pp collisions at s = 8 $$ \sqrt{s}=8 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2017
The production of a Z boson and a photon in association with a high-mass dijet system is studied using 20.2 fb−1 of proton-proton collision data at a centre-of-mass energy of s = 8 $$ \sqrt{s}=8 $$ TeV recorded with the ATLAS detector in 2012 at the ...

Non-minimal CW inflation, electroweak symmetry breaking and the 750 GeV anomaly [PDF]

open access: yes, 2015
A bstractWe study whether the hinted 750 GeV resonance at the LHC can be a Coleman-Weinberg inflaton which is non-minimally coupled to gravity. Since the inflaton must couple to new charged and coloured states to reproduce the LHC diphoton signature, the

The Standard Model in Its Other Phase [PDF]

open access: yes, 1999
The standard model of particle physics is analyzed for the case of a Higgs potential not favoring spontaneous electroweak symmetry breaking to gain insight into the physics of the standard model.

Dynamical mechanism for ultra-light scalar Dark Matter [PDF]

open access: yes, 2011
Assuming a double-well bare potential for a self-interacting scalar field, with the Higgs vacuum expectation value, it is shown that non-perturbative quantum corrections naturally lead to ultra-light particles of mass $\simeq10^{-23}$eV, if these non ...
