Energy-peak based method to measure top quark mass via B-hadron decay lengths

open access: yesJournal of High Energy Physics, 2023
We develop a method for the determination of the top quark mass using the distribution of the decay length of the B-hadrons originating from its decay. This technique is based on our earlier observation regarding the location of the peak of the b quark ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Magnetospectroscopy of shallow donors in two dimensions in the presence of fluctuations of the electrostatic potential

open access: yesNanophotonics
Spectroscopy of shallow donors is a tool to test theoretical models and to reveal properties of semiconductors. In this work we consider intra-shallow impurity transitions by studying a CdTe/(Cd, Mg)Te structure grown by a molecular beam epitaxy in which

Evidence for associated production of a Higgs boson with a top quark pair in final states with electrons, muons, and hadronically decaying τ leptons at s=13 $$ \sqrt{s}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2018
Results of a search for the standard model Higgs boson produced in association with a top quark pair ( tt¯H $$ \mathrm{t}\overline{\mathrm{t}}\mathrm{H} $$) in final states with electrons, muons, and hadronically decaying τ leptons are presented.

Optimising top-quark threshold scan at CLIC using genetic algorithm

open access: yesJournal of High Energy Physics, 2021
One of the important goals at the future e + e − colliders is to measure the top-quark mass and width in a scan of the pair production threshold. However, the shape of the pair-production cross section at the threshold depends also on other model ...

Phosphoinositides and inositol phosphates as molecular glues

open access: yesFEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Utilization of physics computation based on maple in determining the dynamics of tippe top

open access: yesJournal of Physics: Conference Series, 2019
Physics computing can be used to help solve complex dynamic equations, both translation and rotation. The purpose of this research is to obtain the tippe top’s dynamic equation using computational physics based maple. The equation of tippe top motion has

Search for t t ¯ H $$ \mathrm{t}\overline{\mathrm{t}}\mathrm{H} $$ production in the H → b b ¯ $$ \mathrm{H}\to \mathrm{b}\overline{\mathrm{b}} $$ decay channel with leptonic t t ¯ $$ \mathrm{t}\overline{\mathrm{t}} $$ decays in proton-proton collisions at s = 13 $$ \sqrt{s}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2019
A search is presented for the associated production of a standard model Higgs boson with a top quark-antiquark pair ( t t ¯ H $$ \mathrm{t}\overline{\mathrm{t}}\mathrm{H} $$ ), in which the Higgs boson decays into a b quark-antiquark pair, in proton ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
