2. Diffractive Scattering at the LHC

Alexander Lind

This talk will present a study of diffractive scattering of high-energy protons at the LHC. Hadronic diffraction is not well-understood and many alternative approaches exist. The Monte Carlo event generator Pythia follows a Pomeron-based approach, where the invariant mass of the diffractive system and the squared momentum transfer of the system is set up according to a phenomenological Pomeron...

The High Level Trigger (HLT) system used in the ATLAS detector at the
Large Hadron Collider provides high efficiency selection of a wide range of
signals. Very important targeted signatures are those where we identify single
or multiple electron candidate events in the data. This is because they
have a very wide application in many type of physics searches, like Higgs
searches, searches of...

4. Jet tagging with neural networks

The LHC has yet to achieve a discovery more exciting than the Higgs boson
in 2012, but the collaboration has not given up hope of one. In the quest to
observe physics Beyond the Standard Model (BSM) we probe higher luminoci-
ties, and employ new techniques to access previously elusive areas of phase space.
One aspect of the phenomenology that is under active development is the...

5. b-Jet Clustering Techniques for BSM Higgs Physics

Billy Ford

04/04/2019, 11:20

In this talk we consider aspects of beyond the standard model phenomenology involving b-jet classification. In particular, we consider events involving an extended Higgs sector from 2HDMs, which decay into final states of multiple b-jets. We review how these jets are identified and tagged both at the LHC and in Monte Carlo simulation, including so called jet clustering algorithms, and pose the...

6. Bounds and Prospects for Stable Multiply Charged Particles at the LHC

Sandra Kvedaraite

Colored and colorless particles that are stable on collider scales and carry exotic electric charges, so-called MCHSPs, exist in extensions of the Standard Model, and can include the top partner(s) in solutions of the hierarchy problem. In this talk I will present a recast of two production channels of MCHSPs: the “open” channel – where the particles are pair-produced above threshold, and are...

7. Future Prospects of the SNO+ Experiment

Lorna Nolan

04/04/2019, 12:00

The SNO+ experiment is a multi-purpose liquid scintillator neutrino experiment, with a main goal to search for neutrino less double beta decay of 130Te. In preparation for the liquid scintillator phase, the detector has been running with pure water as a detection medium for the past year. During this time, measurements of solar neutrinos with very low backgrounds have been made as well as new...
