Apparent unitarity violation in high mass region of MbW from a “hidden” top partner at high energy colliders

open access: yesPhysics Letters B, 2016
Perturbative unitarity conditions have been playing an important role in estimating the energy scale of new physics, including the Higgs mass as the most important example.

Search for new phenomena in multi-body invariant masses in events with at least one isolated lepton and two jets using s $$ \sqrt{s} $$ = 13 TeV proton–proton collision data collected by the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A search for resonances in events with at least one isolated lepton (e or μ) and two jets is performed using 139 fb −1 of s $$ \sqrt{s} $$ = 13 TeV proton–proton collision data recorded by the ATLAS detector at the LHC. Deviations from a smoothly falling

Gauge invariant metric fluctuations in the early universe from STM theory of gravity: nonperturbative formalism [PDF]

open access: yes, 2007
We develop a nonperturbative quantum field formalism to describe scalar gauge-invariant metric flucturations in the early universe from a 5D apparent (Ricci flat) vacuum.Comment: version accepted in Physics Letters

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Origin of hadron mass from gravitational D-form factor and neutron star measurements

open access: yesPhysics Letters B
Clarifying the origin of hadron mass is one of the fundamental problems in particle physics, relevant from hadronic scales to astrophysical observations. At low energies, this issue is reflected in the decomposition of the hadron mass into chiral-variant

Interacting Two-Time Physics Field Theory With a BRST Gauge Invariant Action

open access: yes, 2006
We construct a field theoretic version of 2T-physics including interactions in an action formalism. The approach is a BRST formulation based on the underlying Sp(2,R)gauge symmetry, and shares some similarities with the approach used to construct string ...

More on complexity of operators in quantum field theory [PDF]

open access: yes, 2019
Recently it has been shown that the complexity of SU($n$) operator is determined by the geodesic length in a bi-invariant Finsler geometry, which is constrained by some symmetries of quantum field theory.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

New physics contributions to moments of inclusive b → c semileptonic decays

open access: yesJournal of High Energy Physics, 2023
Inclusive semileptonic B → X c ℓ ν ¯ ℓ $$ {X}_c\ell {\overline{\nu}}_{\ell } $$ decays, where ℓ = μ, e, are by now standard candles in the determination of the CKM element |V cb |. These determinations rely on the heavy-quark expansion and use moments of
