The CDF dijet excess and Z'_{cs} coupled to the second generation quarks

, 2011
Recently the CDF collaboration has reported the excess in the dijet invariant-mass distribution of the Wjj events, corresponding to a significance of 3.2 standard deviations.

Polo‐like kinase 1–inhibitor co‐complex structures via the surface‐entropy reduction approach and a DARPin‐assisted approach

Acta Crystallographica Section D, Volume 81, Issue 12, Page 718-733, December 2025.
A surface‐entropy reduction approach for human Polo‐like kinase 1 (PLK1) enabled a reproducible and robust crystallization system for this cancer drug target. Co‐crystal structures with representatives of three different small‐molecule inhibitor classes were elucidated.

Xtricorder: a likelihood‐enhanced self‐rotation function and application to a machine learning‐enhanced Matthews prediction of asymmetric unit copy number

Acta Crystallographica Section D, Volume 81, Issue 12, Page 678-692, December 2025.
Xtricorder is a tool for analysing crystallographic data, featuring a likelihood‐enhanced self‐rotation function and a novel `composite‐section diagram' thereof, which aids interpretation and enables a machine learning‐enhanced prediction of asymmetric unit content.Analysis of crystallographic diffraction data after collection and integration but ...

On mass limit for chiral color symmetry $G'$-boson from Tevatron data on $t \bar{t}$ production

, 2010
The contributions of $G'$-boson predicted by the chiral color symmetry of quarks to the cross section $\sigma_{t\bar{t}}$ and to the forward-backward asymmetry $A_{\rm FB}^{p \bar p}$ of $t\bar{t}$ production at the Tevatron are calculated with account ...

On Models of New Physics for the Tevatron Top A_FB [PDF]

, 2011
CDF has observed a top forward-backward asymmetry discrepant with the Standard Model prediction at 3.4 \sigma. We analyze models that could generate the asymmetry, including flavor-violating W's, horizontal Z'_Hs, triplet and sextet diquarks, and ...

Completion of partial structures using Patterson maps with the CrysFormer machine‐learning model

Acta Crystallographica Section D, Volume 81, Issue 12, Page 668-677, December 2025.
We integrate existing machine learning‐based protein structure‐prediction methods with X‐ray crystallography by completing partial structures derived from AlphaFold predictions and the corresponding Patterson map information. The CrysFormer results are promising when applied to an initial data set of 15‐residue fragments in P21 unit cells.Protein ...

Vector and tensor perturbations in Horava-Lifshitz cosmology

, 2010
We study cosmological vector and tensor perturbations in Horava-Lifshitz gravity, adopting the most general Sotiriou-Visser-Weinfurtner generalization without the detailed balance but with projectability condition.

New Constraints from PAMELA anti-proton data on Annihilating and Decaying Dark Matter [PDF]

, 2010
Recently the PAMELA experiment has released its updated anti-proton flux and anti-proton to proton flux ratio data up to energies of ~200GeV. With no clear excess of cosmic ray anti-protons at high energies, one can extend constraints on the production ...

Reconstructing biological molecules with help from video gamers

Acta Crystallographica Section D, Volume 81, Issue 11, Page 598-604, November 2025.
The results of the Foldit citizen science puzzles for crystallographic models and their integration into the PDB‐REDO databank are discussed.Foldit is a citizen science video game in which players tackle a variety of complex biochemistry puzzles. Here, we describe a new series of puzzles in which Foldit players improve the accuracy of models in the ...
