Molecular components in D*s0(2317) and Ds1(2460) mesons

open access: yesEPJ Web of Conferences, 2016
Different experiments have confirmed that the D*s0(2317) and Ds1(2460) mesons are very narrow states located, respectively, below the DK and D*K thresholds. This is markedly in contrast with the expectations of naive quark models and heavy quark symmetry.

Heavy quark physics in the covariant quark model.

open access: yes, 2014
I give a short introduction to the covariant quark model and its applications to heavy quark physics. The special emphasis will be devoted to the semileptonic, rare and radiative decays of the $\Lambda_b$-baryon.

Impaired Fat Metabolism During Exercise in Patients With Methylmalonic and Propionic Acidemia

open access: yesJIMD Reports, Volume 67, Issue 4, July 2026.
ABSTRACT Methylmalonic acidemia (MMA) and propionic acidemia (PA) are inherited metabolic diseases causing deficiency in the catabolism of amino acids, cholesterol, and odd‐chain fatty acids. Both patient groups report exercise intolerance and fatigue.

Top quark measurements in the CMS experiment

open access: yesEPJ Web of Conferences, 2018
Experimental results on top-quark physics obtained at the CMS experiment are reported based on the data recorded at centre-of-mass energy up to 13 TeV. Inclusive and differential cross sections for both top-quark pair and single top-quark production are ...

Search for electroweak production of a vector-like quark decaying to a top quark and a Higgs boson using boosted topologies in fully hadronic final states

open access: yesJournal of High Energy Physics, 2017
A search is performed for electroweak production of a vector-like top quark partner T of charge 2/3 in association with a standard model top or bottom quark, using 2.3 fb−1 of proton-proton collision data at s = 13 $$ \sqrt{s}=13 $$ TeV collected by the ...

Approximate Ricci‐Flat Metrics for Calabi–Yau Manifolds

open access: yesFortschritte der Physik, Volume 74, Issue 7, July 2026.
ABSTRACT We outline a method to determine analytic Kähler potentials with associated approximately Ricci‐flat Kähler metrics on Calabi–Yau manifolds. Key ingredients are numerically calculating Ricci‐flat Kähler potentials via machine learning techniques and fitting the numerical results to Donaldson's ansatz.

In-Depth Study of the Baryon-Quark Phase Transition in Supernova Matter based on the PNJL Quark Model [PDF]

open access: yesIranian Journal of Astronomy and Astrophysics
Determining the equation of state (EOS) of supernova matter is crucial for studying the baryon-quark phase transition (PT) in the inner core of newborn hot neutron stars, thereby deepening the astrophysical investigations on compact objects.

Determinants of Improved Dyspnea and Exercise Tolerance With Nasal High‐Flow O2 Therapy in Fibrotic Interstitial Lung Disease: A Pilot Physiological Study

open access: yesRespirology, Volume 31, Issue 7, Page 732-744, July 2026.
We tested the respective effect of high‐flow and supplemental O2 from nasal high‐flow O2 therapy (NHFO2) on dyspnea and exercise tolerance in fibrotic interstitial lung disease. Supplemental O2 and NHFO2 (but not high‐flow) provided improvements in these outcomes at “iso‐O2 saturation” due to reduced ventilatory requirements.

Peak Fat Oxidation Does Not Increase From Preseason to Competitive Season and Is Not Associated With Physical Performance of Elite Male Football Players

open access: yesScandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 7, July 2026.
ABSTRACT Elite male football players have high peak fat oxidation (PFO), and recently PFO was reported to increase following preseason (PS) training in semi‐professional male players. Whether PFO increases from PS to competitive season (CS) in elite male football players remains unknown.

Manifestation of quark effects in nuclei via bremsstrahlung analysis in the proton-nucleus scattering

open access: yesPhysics Letters B
As is known, the incoherent emission of photons is dominant comparing to the coherent one in proton-nucleus scattering. The incoherent bremsstrahlung is highly sensitive to the magnetic moments of nucleons in nuclei. According to the quark-meson coupling
