Search for top squark pair production in pp collisions at sqrt(s)=13 TeV using single lepton events

Albert M. Sirunyan, +2296 more
TL;DR: In this article, a search for top squark pair production in pp collisions at root s = 13 TeV is performed using events with a single isolated electron or muon, jets, and a large transverse momentum imbalance.

Quantum corrections in Higgs inflation: the real scalar case

TL;DR: In this paper, the authors present a critical discussion of quantum corrections, renormalisation, and the computation of the beta functions and the effective potential in Higgs inflation, and show that the Jordan and Einstein frames are compatible if all mass scales are transformed between the two frames.

Update of the global electroweak fit and constraints on two-Higgs-doublet models

TL;DR: In this article, an update of the global fit of the Standard Model electroweak sector to latest experimental results is presented, including new kinematic top quark and $W$ boson mass measurements from the LHC, a $\sin^2\theta^{\ell}_{\mathrm{eff}}$ result from the Tevatron, and a new evaluation of the hadronic contribution to $\alpha(M_Z^2)$.

Effective theories and measurements at colliders

TL;DR: In this paper, the impact of RGE-induced operator running and mixing effects on measurements performed in the context of an Effective Field Theory extension of the SM was studied and a general analysis strategy was proposed.

Search for a standard model Higgs boson produced in association with a top-quark pair and decaying to bottom quarks using a matrix element method

Vardan Khachatryan, +2159 more
TL;DR: A search for a standard model Higgs boson produced in association with a top-quark pair and decaying to bottom quarks is presented and the results are presented in terms of the measured signal strength modifier.

PYTHIA 6.4 Physics and Manual

TL;DR: The Pythia program as mentioned in this paper can be used to generate high-energy-physics ''events'' (i.e. sets of outgoing particles produced in the interactions between two incoming particles).

The anti-$k_t$ jet clustering algorithm

TL;DR: The anti-k-t algorithm as mentioned in this paper behaves like an idealised cone algorithm, in that jets with only soft fragmentation are conical, active and passive areas are equal, the area anomalous dimensions are zero, the non-global logarithms are those of a rigid boundary and the Milan factor is universal.

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.
