Implications of the CDF t \bar t Forward-Backward Asymmetry for Hard Top Physics

open access: yes, 2011
The CDF collaboration has recently reported a large deviation from the standard model of the t \bar t forward-backward asymmetry in the high invariant mass region.

Relationship between Physical Activity and Physical Fitness in Preschool Children: A Cross-Sectional Study [PDF]

open access: yesBioMed Research International, 2017
Purpose. To evaluate the relationships between objectively measured physical activity and physical fitness among preschool children. Methods. A total of 346 participants (201 boys and 145 girls) aged 3.5–5.5 years (M=4.5 yr, SD = 0.47) from Shanghai, China, completed physical fitness assessments, including triceps skinfold thickness (TSFT), grip ...

Search for new neutral gauge bosons with the CMS Experiment at the LHC

open access: yesEPJ Web of Conferences, 2018
A search for narrow resonances in dimuon invariant mass spectra has been performed using 13 fb-1 data obtained in 2016 from proton-proton collisions at √s = 13 TeV with the CMS experiment at the LHC. No evidence for physics beyond standard model is found.

Unified description of the Aharonov-Bohm effect in isotropic multiband electronic systems

open access: yesPhysical Review Research, 2023
We present a unified treatment of the Aharonov-Bohm (AB) effect for two-dimensional multiband electronic systems possessing isotropic band structures.

Hunting for asymptotia at LHC

open access: yes, 2013
We discuss whether the behaviour of some hadronic quantities, such as the total cross-section, the ratio of the elastic to the total cross-section, are presently exhibiting the asymptotic behaviour expected at very large energies.

Hands‐on protocol for preparing water‐soluble fractions from agri‐food samples for NMR‐based metabolomics analysis

open access: yesFEBS Open Bio, EarlyView.
This research protocol outlines a workflow for nuclear magnetic resonance (NMR)‐based metabolomics in the agri‐food sector. Using two case studies—strawberry leaves (solid matrix) and wine (liquid matrix)—it details the procedures for sample preparation, data acquisition, and processing.

Top quark pair production cross-section results at LHC in final states with tau or no leptons

open access: yes, 2013
ATLAS and CMS measured the top quark pair production inclusive cross section using proton-proton collision data collected at 7 TeV c.m. energy at the LHC during the year 2011 in several channels.
