Kavli Affiliate: Jia Liu | First 5 Authors: Yuxuan He, Jia Liu, Xiaolin Ma, Xiao-Ping Wang, | Summary: We present a scalar-driven sterile neutrino production model where the interaction with the ultralight scalar field modifies the oscillation production of sterile neutrinos in the early universe. The model effectively suppresses the production of sterile neutrinos at […]

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, K. Adamczyk, L. Aggarwal, H. Ahmed | Summary: We report a measurement of the $C!P$-violating parameters $A$ and $S$ in $B^{0}to K_{S}^{0} pi^{0}$ decays at Belle II using a sample of $387times 10^{6}$ $Bbar{B}$ events recorded in $e^{+}e^{-}$ collisions at a center-of-mass […]

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, Mayuko Yamashita, , , | Summary: Inspired by consideration in heterotic string theory, we construct a morphism of spectra from $mathrm{KO}((q))/mathrm{TMF}$ to $Sigma^{-20}I_{mathbb{Z}} mathrm{TMF}$, which we show to be an isomorphism and to implement the Anderson self-duality of $mathrm{TMF}$. We will use this to factor […]

This morphism is then used to define another morphism from $mathrm{TMF}$ to $Sigma^{-20}I_{mathbb{Z}}(mathrm{MSpin}/mathrm{MString})$, […]

Kavli Affiliate: Jia Liu | First 5 Authors: Tian Xia, Jia Liu, Abdel Lisser, , | Summary: This paper considers the distributionally robust chance constrained Markov decision process with random reward and ambiguous reward distribution. We consider individual and joint chance constraint cases with Kullback-Leibler divergence based ambiguity sets centered at elliptical distributions or elliptical […]

Kavli Affiliate: Tom Melia | First 5 Authors: David E. Kaplan, Tom Melia, Surjeet Rajendran, , | Summary: In this and a companion paper, we show that quantum field theories with gauge symmetries permit a broader class of classical dynamics than typically assumed. In this article, we show that the dynamics extracted from the path […]

Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Tenyo Kawamura, Chris Done, Tadayuki Takahashi, , | Summary: Fast variability of the X-ray corona in black hole binaries can produce a soft lag by reverberation, where the reprocessed thermalized disc photons lag behind the illuminating hard X-rays. This lag is small, and systematically decreases with increasing […]
