TLDR
Combined 95% confidence-level upper limits are set on the production cross section for a range of vectorlike quark scenarios, significantly improving upon the reach of the individual searches.
Abstract
A combination of the searches for pair-produced vectorlike partners of the top and bottom quarks in various decay channels (T -> Zt/Wb/Ht, B -> Zb/Wt/Hb) is performed using 36.1 fb(-1) of pp ...

Revisiting the vector leptoquark explanation of the B-physics anomalies

TL;DR: In this article, the vector leptoquark hypothesis was investigated for a combined explanation of the $B$-physics anomalies, and the results showed that a sizable 2-3 family mixing can be achieved in a motivated ultraviolet completion.

CP Violation in the Renormalizable Theory of Weak Interaction

TL;DR: In this article, it was shown that no CP-violating interactions exist in the quartet scheme without introducing any other new fields, and that the strong interaction must be chiral SU ( 4) X SU( 4) invariant as precisely as the conservation of the third component of the iso-spin.

A Brief Introduction to PYTHIA 8.1

TL;DR: PYTHIA 8 represents a complete rewrite in C++, and does not yet in every respect replace the old code, but does contain some new physics aspects that should make it an attractive option especially for LHC physics studies.

Unitary Symmetry and Leptonic Decays

TL;DR: In this article, an analysis of leptonic decays based on unitary symmetry for strong interactions and the V-A theory for weak interactions is presented, and an explanation for the observed predominance of the LAMBDA yields + e/sup -/ + nu decay over the lamBDA /sup −/ yields n + e /sup + n decay.

Parton distributions for the LHC

TL;DR: In this paper, the authors presented an updated leading-order, next-to-leading order and next-next-ordering order parton distribution function (MSTW 2008) determined from global analysis of hard-scattering data within the standard framework of leading-twist fixed-order collinear factorisation in the $\overline{\mathrm{MS}}$¯¯$¯¯¯¯¯
