A new mechanism for matter-antimatter asymmetry and connection with dark matter
Arnab Dasgupta, P. S. Bhupal Dev, Sin Kyu Kang +1
We propose a new mechanism for generating matter-antimatter asymmetry via the interference of tree-level diagrams only, where the imaginary part of the Breit-Wigner propagator for…
Consistent and Efficient Pricing of SPX and VIX Options under Multiscale Stochastic Volatility
Jaegi Jeon, Geonwoo Kim, Jeonggyu Huh
This study provides a consistent and efficient pricing method for both Standard & Poor's 500 Index (SPX) options and the Chicago Board Options Exchange's Volatility Index (VIX) opt…
A theory for scotogenic dark matter stabilised by residual gauge symmetry
Julio Leite, Oleg Popov, Rahul Srivastava +1
Dark matter stability can result from a residual matter-parity symmetry, following naturally from the spontaneous breaking of the gauge symmetry. Here we explore this idea in the c…
Exotic decays of top partners: mind the search gap
Giacomo Cacciapaglia, Thomas Flacke, Myeonghun Park +1
Many standard model extensions, including composite Goldstone Higgs models, predict vector-like fermionic top-partners at the TeV scale. The intensive search programmes by ATLAS an…
A modular symmetric scotogenic model
Takaaki Nomura, Hiroshi Okada, Oleg Popov
We propose a minimal extention of the Standard Model where neutrino masses are generated radiatively at one-loop level via Scotogenic scanario. The model is augmented with mo…
Connecting ANITA Anomalous Events to a Non-thermal Dark Matter Scenario
Debasish Borah, Arnab Dasgupta, Ujjal Kumar Dey +1
The ANtarctic Impulsive Transient Antenna (ANITA) collaboration has observed two EeV-energy, upward going events originating from below the horizon. As no standard model (SM) parti…
Analytic crystals of solitons in the four dimensional gauged non-linear sigma model
Fabrizio Canfora, Seung Hun Oh, Aldo Vera
The first analytic topologically non-trivial solutions in the (3+1)-dimensional gauged non-linear sigma model representing multi-solitons at finite volume with manifest ordered str…
as a single leptoquark solution to and
Oleg Popov, Michael A. Schmidt, Graham White
We show that, up to plausible uncertainties in BR, the leptoquark can simultaneously explain the observation of anomalies in and with…
Roles of sterile neutrinos in particle physics and cosmology
Sin Kyu Kang
The impacts of the light sterile neutrino hypothesis in particle physics and cosmology are reviewed. The observed short baseline neutrino anomalies challenging the standard explana…
Portraying Double Higgs at the Large Hadron Collider
Jeong Han Kim, Minho Kim, Kyoungchul Kong +2
We examine the discovery potential for double Higgs production at the high luminosity LHC in the final state with two -tagged jets, two leptons and missing transverse momentum.…
Radiative Dirac Neutrino Mass with Dark Matter and it's implication to in the extension of the Standard Model
Arnab Dasgupta, Sin Kyu Kang, Oleg Popov
The Standard Model gauge symmetry is extended by which when spontaneously broken leads to residual symmetry. gauge symmetry made anomaly fr…
FickleNet: Weakly and Semi-supervised Semantic Image Segmentation using Stochastic Inference
Jungbeom Lee, Eunji Kim, Sungmin Lee +2
The main obstacle to weakly supervised semantic image segmentation is the difficulty of obtaining pixel-level information from coarse image-level annotations. Most methods based on…
Two-component Dark Matter with co-genesis of Baryon Asymmetry of the Universe
Debasish Borah, Arnab Dasgupta, Sin Kyu Kang
We discuss the possibility of realising a two-component dark matter (DM) scenario where the two DM candidates differ from each other by virtue of their production mechanism in the…
A Model of Neutrino Anomalies and IceCube data
Y. H. Ahn, Sin Kyu Kang
We interpret the neutrino anomalies in neutrino oscillation experiments and the high energy neutrino events at IceCube in terms of neutrino oscillations in an extension of the stan…
Relevance Factor VAE: Learning and Identifying Disentangled Factors
Minyoung Kim, Yuting Wang, Pritish Sahu +1
We propose a novel VAE-based deep auto-encoder model that can learn disentangled latent representations in a fully unsupervised manner, endowed with the ability to identify all mea…
Scotogenic dark matter stability from gauged matter parity
Sin Kyu Kang, Oleg Popov, Rahul Srivastava +2
We explore the idea that dark matter stability results from the presence of a matter-parity symmetry, arising naturally as a consequence of the spontaneous breaking of an extended…
