    Damon Cleaver (King's College London)

    Dark matter with masses beyond the Planck scale pose a direct detection challenge given their very low flux. There have been attempts to constrain macroscopic scale dark matter using large volume terrestrial mediums such as the atmosphere, and long integration time mediums such as ancient mica. In this talk, I show that searches of macroscopic dark matter using $\mathcal{O}(\text{100 km}^3)$...

  6. 2. Non-decoupling scalars at future detectors
    Graeme Crawford
    15/07/2024, 16:50

    The nature of the electroweak symmetry breaking remains the last theoretical unknown of the Standard Model (SM). In this work, we extend the SM with a set of simplified scalar models which are classified by their electroweak irreducible representations. We present a no-lose theorem for future experiments by showing that any additional particle to the SM that acquires a significant fraction of...

  7. 7. The Double Copy: A Duality for Particles and Gravity
    Kymani Armstrong-Williams (Queen Mary University of London)
    15/07/2024, 17:10

    An open problem in theoretical physics is to combine all four of the fundamental forces of nature into one single theory. Problematically, gravity has proven difficult to reconcile with the other forces. Recently, relationships between scattering amplitudes (the quantity related to the probability for an interaction to occur between two or more particles) in non-abelian gauge theories (such as...

    Although there is no concrete evidence of physics beyond the Standard Model at the LHC, there is still a great deal of potential to be explored. Taking advantage of the upgraded detectors and the higher integrated luminosity expected in future runs is critical for uncovering novel phenomena at the LHC.

    Our research is looking for pairs of light Higgs bosons ($H_1$) through SUSY cascade...

  19. 6. Primordial Black hole relics as Dark matter candidate
    Amirah Saeed M. Aljazaeri (University of Sussex)
    17/07/2024, 17:50

    During the talk, I will delve into the unique candidate of Planck mass Primordial Black Hole (PBH) relics as dark matter. These relics, arising from the evaporation of light PBHs with initial masses ranging from 1g to approximately 10^6g, possess the potential to account for the entirety of dark matter in our universe. My presentation will encompass a thorough review of existing constraints on...

  20. 8. Spherically symmetric Einstein-aether gravity
    Mr Arthur Yi-Hsiung Hsu (University of Cambridge)
    17/07/2024, 18:10

    In this talk, I will address the Einstein-aether theory (EAE). This theory is an ancestor to the aether-scalar-tensor theory (AEST), which is currently considered the most promising relativistic completion of Modified Newtonian Dynamics (MOND). By studying EAE, we can gain valuable insights into the more complicated AEST. First, I will present a new a gauge freedom within the spherically...

  24. 4. Underlying Event Tuning for VINCIA
    Baris Tuncay (University of Oxford (GB))
    18/07/2024, 11:30

    Underlying event (UE) modelling is crucial at the LHC, for both precision Standard Model measurements and understanding of soft QCD phenomenology. In recent years, an emergence of newer, improved parton shower models in Monte Carlo generators were seen. One such model is VINCIA, an antenna-based parton shower model that was developed as a plug-in to Pythia. Incorporating both soft and...

  25. 5. Low energy electron recoil searches within LZ and using FlameNEST for future work
    Harkirat Riyat (University of Edinburg)
    18/07/2024, 11:50

    LUX-ZEPLIN (LZ) is a direct dark matter (DM) detection experiment utilising a 7-tonne active target of liquid xenon, searching primarily for WIMP candidates that produce nuclear recoils (NR) of xenon
    nuclei. LZ recently published results from the 60 live-day science run one (SR1), producing new world-leading limits for the upper bound of the spin-independent and neutron spin-dependent...
