The Phases of Non-supersymmetric Gauge Theories: the $SO(N_c)$ Case Study

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Csaba Csáki, Andrew Gomes, Hitoshi Murayama, Ofri Telem, | Summary: We investigate the IR phases of non-supersymmetric (non-SUSY) $SO(N_c)$ gauge theories with $N_F$ fermions in the vector representation obtained by perturbing the SUSY theory with anomaly mediated SUSY breaking (AMSB). We find that of the wide variety […]

The relative contribution to heavy metals production from binary neutron star mergers and neutron star-black hole mergers

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Hsin-Yu Chen, Salvatore Vitale, Francois Foucart, , | Summary: The origin of the heavy elements in the Universe is not fully determined. Neutron star-black hole (NSBH) and {binary neutron star} (BNS) mergers may both produce heavy elements via rapid neutron-capture (r-process). We use the recent detection of […]

The Stellar Initial Mass Function and Population Properties of M89 from Optical and NIR Spectroscopy: Addressing Biases in Spectral Index Analysis

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Ilaria Lonoce, Anja Feldmeier-Krause, Wendy L. Freedman, , | Summary: The complexity of constraining the stellar initial mass function (IMF) in early-type galaxies cannot be overstated, given the necessity of both very high signal-to-noise (S/N) data and the difficulty of breaking the strong degeneracies that occur […]

A shock near the virial radius of the Perseus Cluster

Kavli Affiliate: Steven W. Allen | First 5 Authors: Zhenlin Zhu, Aurora Simionescu, Hiroki Akamatsu, Xiaoyuan Zhang, Jelle S. Kaastra | Summary: Previous X-ray studies of the Perseus Cluster, consisting of 85 Suzaku pointings along eight azimuthal directions, revealed a particularly steep decrease in the projected temperature profile near the virial radius (~r200) towards the […]

To investigate the magnetic-field-induced distortion of NSs through GRB X-ray plateaus

Kavli Affiliate: Renxin Xu | First 5 Authors: Tingting Lin, Shuang Du, Renxin Xu, , | Summary: Magnetic field may distort neutron stars (NSs), but the effect has not been robustly tested through gravitational-wave observation yet due to the absence of a fast rotating Galactic magnetar. The central objects of Gamma-ray bursts (GRBs) could be […]

Investigating magnetically-induced distortions of neutron stars through gamma-ray burst X-ray plateaus

Kavli Affiliate: Renxin Xu | First 5 Authors: Tingting Lin, Shuang Du, Weihua Wang, Shujin Hou, Renxin Xu | Summary: Magnetic field may distort neutron stars (NSs), but its effect has not been robustly tested through gravitational-wave observation yet due to the absence of a fast rotating Galactic magnetar. Part of gamma-ray bursts (GRBs) are […]

Lattice Renormalization of Quantum Simulations

Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Henry Lamm, Ying-Ying Li, Wanqiang Liu, | Summary: With advances in quantum computing, new opportunities arise to tackle challenging calculations in quantum field theory. We show that trotterized time-evolution operators can be related by analytic continuation to the Euclidean transfer matrix on an anisotropic lattice. […]

Neutrino constraints on long-lived heavy dark sector particle decays in the Earth

Kavli Affiliate: Angela V. Olinto | First 5 Authors: Mary Hall Reno, Luis A. Anchordoqui, Atri Bhattacharya, Austin Cummings, Johannes Eser | Summary: Recent theoretical work has explored dark matter accumulation in the Earth and its drift towards the center of the Earth that, for the current age of the Earth, does not necessarily result […]
