Radioactivity of quark nuggets

open access: yesJournal of High Energy Physics
Quark nuggets Q Z A $$ {}_{\textrm{Z}}{}^{\textrm{A}}\textrm{Q} $$ , as Fermionic non-topological solitons, could have their mass per baryon smaller than ordinary nuclei and behave as exotic nuclei with different relations of atomic number and atomic ...

The non-perturbative unquenched quark model

open access: yesEPJ Web of Conferences, 2017
In recent years states in the quarkonium spectrum not expected in the naive quark model have appeared and created a lot of interest. In the theoretical side the study of the effect of meson-meson thresholds in the spectrum have been performed in ...

Core collapse supernovae in the QCD phase diagram

open access: yes, 2011
We compare two classes of hybrid equations of state with a hadron-to-quark matter phase transition in their application to core collapse supernova simulations.

Is distinct location evidence of distinct objects? Multilocation and the problem of parsimony

open access: yesAnalytic Philosophy, Volume 66, Issue 3, Page 394-401, September 2025.
Abstract For an object to be multilocated is for it to wholly occupy disjoint spatial regions simultaneously. If multilocation is possible, it is possible that a multilocated particle is wholly located at 1080 distinct locations, such that it constitutes a particle‐for‐particle duplicate of the actual universe.

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 ...

A relativistic treatment of pion wave functions in the annihilation antiproton-proton -> pi^-pi^+

open access: yes, 2004
Quark model intrinsic wave functions of highly energetic pions in the reaction \bar pp->\pi^-\pi^+ are subjected to a relativistic treatment. The annihilation is described in a constituent quark model with A2 and R2 flavor-flux topology and the ...

Investigating the Modulation of Corticomotor and Neuromuscular Function by Contralateral and Ipsilateral Experimental Pain Applied During Cycling

open access: yesScandinavian Journal of Medicine &Science in Sports, Volume 35, Issue 9, September 2025.
ABSTRACT Pain can impair exercise performance, but its influence on motor control, in particular the effect of robust experimental pain on the timecourse of corticomotor responses throughout prolonged, exhaustive cycling, remains unclear. We tested the hypothesis that an augmented experimental pain intervention applied to exercising and non‐exercising ...

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.

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 ...

Quantum Thermalization Dynamics of Fermi Gases Quenched to the BEC‐BCS Crossover

open access: yesAdvanced Science, Volume 12, Issue 31, August 21, 2025.
This study, reporting the first experimental realization of interaction quench far faster than the Fermi timescale in fermionic many‐body systems, explores real‐time quantum thermalization dynamics in the BEC‐BCS crossover. It observes prethermal states with distinct lifetimes after quantum quench, uncovers universal prethermal scaling, and observes ...
