Unraveling the Particle World and the Cosmos at Berkeley—Workshop in Honor of Lawrence Hall and Hitoshi Murayama

26 Sept 2024, 08:00 → 28 Sept 2024, 12:20 US/Pacific

David Brower Center in downtown Berkeley

The Berkeley Center for Theoretical Physics at UC Berkeley and LBNL will host a workshop celebrating the distinguished careers of Professors Lawrence Hall and Hitoshi Murayama.

The event will kick off on Thursday morning and conclude before lunch on Saturday. It will be held at the David Brower Center (link is external)in Downtown Berkeley. A schedule for the event will be available soon. 

While talks are by invitation only, we will have a poster session for which we encourage contributions. See "submit abstract" button below or "poster session" tab on the left.

The registration fee covers our use of the conference center as well as breakfast and lunch on Thursday and Friday, and breakfast on Saturday.

Thursday 26 September ¶

08:00 → 09:00 Breakfast

09:00 → 09:05 Welcome¶

Speaker: Steven Kahn

09:05 → 09:10 Welcome¶

Speaker: Natalie Roe

09:10 → 09:50 Atomic effects relevant in the scattering of high energy leptons (e.g., neutrinos or muons) off atomic electrons¶

I discuss the scattering of high energy leptons off atomic electrons. The focus of the talk is on how the cross section for this process differs from the scattering off free electrons. This involves, atomic binding corrections, Coulomb exchanges between the outgoing energetic struck electron with the remaining atomic debris and other effects. This is not beyond the standard model (BSM) physics, but the results may be relevant for experiments that constrain possible BSM physics.

09:50 → 10:30 Baryogenesis with only the Standard Model CP violation¶

Mesogenesis with a Morphing Mediator (3M) is a new proposal for baryogenesis and dark matter production in which, contrary to common lore, the Standard Model CP violation is sufficient to generate the entire primordial asymmetry of matter over antimatter. Furthermore, the dark sector dynamics of this mechanism produce gravitational waves that can be probed with current and future Pulsar Timing Arrays. 3M-baryogenesis is based on Mesogenesis mechanisms which leverage the CP violation in charged or neutral Standard Model meson systems. I will first give an overview of existing mechanisms of Mesogenesis (their respective signals and features), and discuss general ongoing and proposed search strategies (at colliders, neutrino detectors and more), before introducing the new 3M mechanism.

16:40 → 17:20 Dark matter detection using superconducting qubits¶

Detection of wave-like dark matter using superconducting qubits is
proposed. Due to their capacitive coupling with external electric
fields, superconducting qubits are well-suited for detecting dark
matter candidates such as hidden photons or axions, which induce
effective electric fields. I will discuss the expected sensitivity in
the search of these dark matter candidates using superconducting
qubits as quantum sensors. I will also explore a possibility to
enhance the signal rate with the help of the quantum coherence in
qubits.

11:30 → 12:10 Impacts and Imprints of Axion Dynamics¶

We discovered that the (QCD) axion’s novel evolution, an oscillation or a rotation in field space, can address cosmological mysteries of the Universe. Oscillations can give rise to a new origin of dark matter via parametric resonance. Rotation dynamics may naturally arise as a result of quantum gravity effects and cosmic inflation. This talk will explore the example where axion rotations contribute to axion dark matter through kinetic misalignment and can generate the observed baryon asymmetry of the Universe via axiogenesis. Remarkably, rich phenomenology automatically arises with sharp, distinct, and correlated predictions, including stronger interactions, unique gravitational wave signals, correlated mass scales of supersymmetry and neutrinos, and dark matter gravitational lensing. Thus far, novel axion dynamics have added fuel to experimental efforts and paved new theory research avenues.
