Higgs Boson Spectra in Supersymmetric Left-Right Models
K. S. Babu, Ayon Patra
We present a comprehensive analysis of the Higgs boson spectra in several versions of the supersymmetric left--right model based on the gauge symmetry $SU(3)_c \times SU(2)_L \time…
keV Sterile Neutrino Dark Matter and Low Scale Leptogenesis
Sin Kyu Kang, Ayon Patra
We consider a simple extension of the Standard Model to consistently explain the observation of a peak in the galactic X-ray spectrum at 3.55 keV and the light neutrino masses alon…
On the asymptotic behavior of unimodal rank generating functions
Kathrin Bringmann, Byungchan Kim
In a recent paper, J. Lovejoy and the second author conjectured that ranks for four types of unimodal like sequences satisfy certain inequalities. In this paper, we prove these con…
IceCube events and decaying dark matter: hints and constraints
Arman Esmaili, Sin Kyu Kang, Pasquale Dario Serpico
In the light of the new IceCube data on the (yet unidentified) astrophysical neutrino flux in the PeV and sub-PeV range, we present an update on the status of decaying dark matter…
An overpartition analogue of the -binomial coefficients
Jehanne Dousse, Byungchan Kim
We define an overpartition analogue of Gaussian polynomials (also known as -binomial coefficients) as a generating function for the number of overpartitions fitting inside the $…
Probing Large Extra Dimensions With IceCube
Arman Esmaili, O. L. G. Peres, Zahra Tabrizi
In models with Large Extra Dimensions the smallness of neutrino masses can be naturally explained by introducing gauge singlet fermions which propagate in the bulk. The Kaluza-Klei…
Interference Alignment for Multicell Multiuser MIMO Uplink Channels
Khanh Pham, Kyungchun Lee
This paper proposes a linear interference alignment (IA) scheme which can be used for uplink channels in a general multicell multiuser MIMO cellular network. The proposed scheme ai…
Four-neutrino analysis of 1.5km-baseline reactor antineutrino oscillations
Sin Kyu Kang, Yeong-Duk Kim, Young-Ju Ko +1
The masses of sterile neutrinos are not yet known, and depending on the orders of magnitudes, their existence may explain reactor anomalies or the spectral shape of reactor neutrin…
Dissections of a "strange" function
Scott Ahlgren, Byungchan Kim
The "strange" function of Kontsevich and Zagier is defined by \[F(q):=\sum_{n=0}^\infty(1-q)(1-q^2)\dots(1-q^n).\] This series is defined only when is a root of unity, and prov…
Tensor-to-Scalar Ratio in Eddington-inspired Born-Infeld Inflation
Inyong Cho, Naveen K. Singh
We investigate the scalar perturbation of the inflation model driven by a massive-scalar field in Eddington-inspired Born-Infeld gravity. We focus on the perturbation at the attrac…
Renormalization Group Evolution of Neutrino Parameters in Presence of Seesaw Threshold Effects and Majorana Phases
Shivani Gupta, Sin Kyu Kang, C. S. Kim
We examine the renormalization group evolution (RGE) for different mixing scenarios in the presence of seesaw threshold effects from high energy scale (GUT) to the low electroweak…
Prediction of leptonic CP phase from perturbatively modified tribimaximal (or bimaximal) mixing
Sin Kyu Kang, C. S. Kim
We consider the perturbatively modified tribimaximal (or bimaximal) mixing to estimate the (Dirac-type) CP phase in neutrino mixing matrix. The expressions for the CP phase are der…
Inflationary Tensor Perturbation in Eddington-inspired Born-Infeld gravity
Inyong Cho, Hyeong-Chan Kim
We investigate the tensor perturbation in the inflation model driven by a massive-scalar field in Eddington-inspired Born-Infeld gravity. For short wave-length modes, the perturbat…
Constraining the Violation of Equivalence Principle with IceCube Atmospheric Neutrino Data
A. Esmaili, D. R. Gratieri, M. M. Guzzo +3
The recent high-statistics high-energy atmospheric neutrino data collected by IceCube open a new window to probe new physics scenarios that are suppressed in lower energy neutrino…
Impact of sterile neutrinos on the early time flux from a galactic supernova
Arman Esmaili, O. L. G. Peres, Pasquale Dario Serpico
We study the impact of the existence of an eV-mass scale sterile neutrino---with parameters in the ballpark of what is required to fit the laboratory anomalies---on the early time…
Distributed and Centralized Hybrid CSMA/CA-TDMA Schemes for Single-Hop Wireless Networks
Bharat Shrestha, Ekram Hossain, Kae Won Choi
The strength of carrier-sense multiple access with collision avoidance (CSMA/CA) can be combined with that of time-division multiple access (TDMA) to enhance the channel access per…
Production of Stoponium at the LHC
Chul Kim, Ahmad Idilbi, Thomas Mehen +1
Although the Large Hadron Collider (LHC) has not observed supersymmetric (SUSY) partners of the Standard Model particles, their existence is not ruled out yet. One recently explore…
