Anti-SARS-CoV-2 IgM Secondary Response Was Suppressed by Preexisting Immunity in Vaccinees: A Prospective, Longitudinal Cohort Study over 456 Days

open access: yesVaccines, 2023
To obtain more insight into IgM in anti-SARS-CoV-2 immunity a prospective cohort study was carried out in 32 volunteers to longitudinally profile the kinetics of the anti-SARS-CoV-2 IgM response induced by administration of a three-dose inactivated SARS ...

Measurements of Higgs boson production cross sections and couplings in the diphoton decay channel at s $$ \sqrt{\mathrm{s}} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2021
Measurements of Higgs boson production cross sections and couplings in events where the Higgs boson decays into a pair of photons are reported. Events are selected from a sample of proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV collected by the ...

Cosmic Inflation and Genetic Algorithms

open access: yesFortschritte der Physik, Volume 71, Issue 1, January 2023., 2023
Abstract Large classes of standard single‐field slow‐roll inflationary models consistent with the required number of e‐folds, the current bounds on the spectral index of scalar perturbations, the tensor‐to‐scalar ratio, and the scale of inflation can be efficiently constructed using genetic algorithms.

Active Learning in Physics: From 101, to Progress, and Perspective

open access: yesAdvanced Quantum Technologies, EarlyView., 2023
In this review, the concept of active learning is introduced to the physicists at the level of beginner without requirement on background in machine learning. It includes most of the latest applications of active learning in branches of physics, covering but not being limited to quantum information, high energy physics, and condensed matter physics. It

Boson–Boson Interactions at the LHC

open access: yesAnnual Review of Nuclear and Particle Science, 2023
Vector boson scattering is a key production process to probe the electroweak symmetry breaking of the Standard Model and is one of the most important topics of the physics program for the HL-LHC since it involves both self-couplings of vector bosons and their coupling with the Higgs boson.

Benefits of Open Quantum Systems for Quantum Machine Learning

open access: yesAdvanced Quantum Technologies, EarlyView., 2023
Quantum machine learning (QML), poised to transform data processing, faces challenges from environmental noise and dissipation. While traditional efforts seek to combat these hindrances, this perspective proposes harnessing them for potential advantages. Surprisingly, under certain conditions, noise and dissipation can benefit QML.

Boson-boson mixtures and triplet correlations [PDF]

open access: yesPhysical Review B, 1984
The hypernetted-chain formalism for boson-boson mixtures described by an extended Jastrow correlated wave function is derived, taking into account elementary diagrams and triplet correlations. The energy of an ideal boson 3He-4He mixture is computed for low values of the 3He concentration.

BOSONIC TOPCOLOR [PDF]

open access: yesInternational Journal of Modern Physics A, 2001
A topcolor model is presented that contains both composite and fundamental scalar fields. Strong dynamics accounts for most of the top quark mass and part of the electroweak symmetry breaking scale. The fundamental scalar is weakly coupled and transmits its share of electroweak symmetry breaking to the light fermions.
