Near-conformal dynamics in a chirally broken system
Thomas Appelquist, Richard C. Brower, Kimmy K. Cushman +11
Composite Higgs models must exhibit very different dynamics from quantum chromodynamics (QCD) regardless whether they describe the Higgs boson as a dilatonlike state or a pseudo-Na…
Stealth dark matter confinement transition and gravitational waves
R. C. Brower, K. Cushman, G. T. Fleming +11
We use non-perturbative lattice calculations to investigate the finite-temperature confinement transition of stealth dark matter, focusing on the regime in which this early-univers…
Automated label flows for excited states of correlation functions in lattice gauge theory
Kimmy K. Cushman, George T. Fleming
Extracting excited states from lattice gauge theory correlation functions can be achieved through chi-squared minimization fits or algebraic approaches such as the variational meth…
Prony methods for extracting excited states
Kimmy K. Cushman, George T. Fleming
We propose an algebraic method for extracting excited states from lattice gauge theory correlation functions. Instead of fitting to a sum of decaying exponentials, we adopt a varia…
Charge symmetry violation in the doubly charmed cascade masses
K. K. Cushman, A. W. Thomas, R. D. Young
We investigate the electromagnetic contribution to the charge symmetry breaking in the baryon masses using a subtracted dispersion relation based on the Cottingham formula…
