ATLAS presents a strategy for a general search of new physics

One of the main goals of the Large Hadron Collider is to look for signals beyond the Standard Model (the other major goal has already been fulfilled with the discovery of the Higgs boson). To this day scientists are still lacking clues. Could it be…

Precise timing detectors for the LHC experiments

The ATLAS and CMS experiments physics programme at the HL-LHC will target a very wide range of measurements, including in-depth studies of the Higgs boson properties and direct searches for physics beyond the standard model (BSM). Timing detectors…

Heavy-ion collisions at Quark Matter 2018

CERN experiments presented their latest results from the study of lead-ion collisions at the annual Quark Matter conference, that was held this year in Venice, Italy. The programme includes a plethora of presentations on a variety of topics,…

New season starts for the LHC experiments

The last 2017 proton-proton collisions took place on 28 November and the LHC machine was shut down during the winter period to allow for planned technical interventions while the LHC experiments profit from this period to perform maintenance work on…

Connecting the dots: applying deep learning techniques in HEP

With massive amounts of computational power, machines can now recognize objects and translate speech in real time. Deep-learning software attempts to mimic the activity in layers of neurons in the neocortex, the wrinkly 80 percent of the brain where…

LHC experiments present results in Moriond Conference

This year saw the 53rd meeting in the series "Les Rencontres de Moriond". ATLAS and CMS presented impressive results (see pictures) of searches for new phenomena, setting boundaries to where the new physics can still exist. These limits severely…

ATLAS further investigates the width of top quark

The top quark is the heaviest known elementary particle and completes the quark sector of the standard model (SM). Like other fermions in the standard model (SM), it decays through the electroweak interaction. But unlike b and c quarks, which form…

Searching for leptoquarks at the LHC

Last month, Admir Greljo (University of Mainz) and Abdollah Mohammad (Kansas State University, US) during the Collider Cross Talk, gave a comprehensive overview of the theoretical and experimental aspects in leptoquarks searches. Leptoquarks are…

ATLAS observes Higgs boson produced in association with top quarks

The ATLAS collaboration presented the first evidence of “ttH production”, a rare process where a pair of top quarks emits a Higgs boson. Observing this process would provide new insight into the Higgs mechanism and allow for new studies of how…

Electroweak boson pairs offer new approach to searches for New Physics

During the past decades, the Standard Model (SM) of particle physics that explains how the basic building blocks of matter interact is scrutinised by high energy physics experiments. Along with the remarkable success of the SM, there are compelling…
