Flowing Gauge Theories: Finite-Density $QE D_{1 + 1}$

Henry Lamm

Finite-density calculations in lattice field theory are typically plagued by sign problems. A promising way to ameliorate this issue is the holomorphic flow equations that deform t…

Scouring meson decays for true muonium

Yao Ji, Henry Lamm

Rare meson decay experiments promise to measure branching ratios as small as $1 0^{- 13}$ . This presents an opportunity to discover the $μ^{+} μ^{-}$ bound state true muonium. We consider…

Model-Independent Bounds on $R (J / ψ)$ via Dispersive Relations

Henry Lamm

Model-independent bounds on $R (J / ψ) \equiv B R (B_{c}^{+} \to J / ψ τ^{+} ν_{τ}) /$ $B R (B_{c}^{+} \to J / ψ μ^{+} ν_{μ})$ are obtained through a combination o…

Fermions at Finite Density in (2+1)d with Sign-Optimized Manifolds

Andrei Alexandru, Paulo F. Bedaque, Henry Lamm +2

We present Monte Carlo calculations of the thermodynamics of the (2+1) dimensional Thirring model at finite density. We bypass the sign problem by deforming the domain of integrati…

Model-Independent Prediction of $R (η_{c})$

Anson Berns, Henry Lamm

We present a model-independent prediction for $R (η_{c}) \equiv B R (B_{c} \to η_{c} τ^{+} ν_{τ}) / B R (B_{c} \to η_{c} μ^{+} ν_{μ})$ . This prediction is o…

Tests of the Standard Model in $B \to D ℓ ν_{ℓ}$ , $B \to D^{*} ℓ ν_{ℓ}$ and $B_{c} \to J / ψ ℓ ν_{ℓ}$

Thomas D. Cohen, Henry Lamm, Richard F. Lebed

A number of recent experimental measurements suggest the possibility of a breakdown of lepton ( $ℓ$ ) universality in exclusive $b \to c ℓ ν_{ℓ}$ semileptonic meson decays. We…

Finite Density $QE D_{1 + 1}$ Near Lefschetz Thimbles

Andrei Alexandru, Gokce Basar, Paulo F. Bedaque +2

One strategy for reducing the sign problem in finite-density field theories is to deform the path integral contour from real to complex fields. If the deformed manifold is the appr…

Simulation of Nonequilibrium Dynamics on a Quantum Computer

Henry Lamm, Scott Lawrence

We present a hybrid quantum-classical algorithm for the time evolution of out-of-equilibrium thermal states. The method depends upon classically computing a sparse approximation to…

Finite-Density Monte Carlo Calculations on Sign-Optimized Manifolds

Andrei Alexandru, Paulo Bedaque, Henry Lamm +1

We present a general technique for addressing sign problems that arise in Monte Carlo simulations of field theories. This method deforms the domain of the path integral to a manifo…
