6. Quantum analysis of the minimal realistic SO(10) model

Katerina Jarkovska

The minimal renormalizable realization of $SO(10)$ model is an intriguing candidate for realistic extension of the Standard model. As the $SO(10)$ symmetry breaking is caused by the adjoint representation, the dominant GUT-scale-influencing gravitational effects are suppressed allowing for significantly improved proton lifetime calculations.
We present results of the thorough model’s...

44. Composite quarks and leptons with low-scale SO(10) unification

Benoit Assi

We propose a chiral gauge theory in which the Standard Model (SM) quarks and leptons are composite fields. The theory is based on an $SU(15)$ gauge symmetry that confines the preons and predicts exactly 3 generations of SM fermions. Certain vectorlike quarks and leptons are also formed, and may be within the reach of the LHC. We discuss the running of the SM gauge couplings to 3-loop order,...

124. Observable proton decay in Flipped SU(5)

Ms Maria Mehmood (Quaid-i-Azam University, Islamabad, Pakistan)

We explore proton decay in a class of realistic supersymmetric flipped $SU(5)$ models supplemented by a $U(1)_R$ symmetry which plays an essential role in implementing hybrid inflation. Two distinct neutrino mass models, based on inverse seesaw and type I seesaw, are identified, with the latter arising from the breaking of $U(1)_R$ by nonrenormalizable superpotential terms. Depending on the...

130. Semisimple extensions of the Standard Model

Joseph Tooby-Smith

You are probably aware that the Standard Model can fit into su(5), so(10) and Pati-Salam. But did you know it can also fit into: su(4)+sp(4)+su(5)+su(2)+su(2). Probably not. Should you care? Also probably not. But what if I said, that without adding additional fermions (except 3 RHN), then there are only 340 semi-simple algebras the SM can actually fit into. This talk will tell the story...

69. Learning the composition of Ultra-High Energy Cosmic Rays

Michele Tammaro

We use use statistical inference to derive the mass composition of Pierre Auger Open Data at different energies. We simulate showers for all elements between proton and iron and use them to train a set of classifiers, each one trained to distinguish set of primaries by their 𝑋𝑚𝑎𝑥 distributions. By unfolding this data, we can obtain the most probable mass composition distribution for each...

118. Simulation and Indirect Detection of Dark Glueball Showers

Caleb Gemmell (University of Toronto)

10/05/2022, 15:15

Parton showers are part and parcel of particle phenomenology, but what in the case of a confining dark sector with no light quarks below the confinement scale? Then the only available hadronic states are ‘glueballs’, composite gluon states. To date, there have been very few quantitative studies of dark shower signatures with glueball final states, despite the fact they commonly appear in...

210. Simple, Interpretable Anomaly Detectors

Layne Bradshaw

10/05/2022, 15:30

Anomaly detection with autoencoders is a popular method to search for new physics in a model-agnostic manner.
In this talk, we try to understand these "black boxes" by designing mimickers with a small number of energy flow polynomials as inputs.
These mimickers perform comparably to the autoencoder when ordering background events, but also match the anomaly detection capabilities of the...

236. FCNC in Concurrent Dark Photon & Dark Z Models

Lopamudra Mukherjee (University of Mississippi)

10/05/2022, 15:45

In this work we consider FCNC constraints on concurrent dark vector boson models simulatneously from B and K decays. Both the dark photon and the dark Z generate FCNC processes through loops due to kinetic mixing with the SM photon and Z boson respectively. Previously, the FCNC amplitudes with the dark photon and dark Z decays were calculated without the dipole term in the amplitude. Also,...
