Supersymmetric Seesaw without Singlet Neutrinos: Neutrino Masses and Lepton-Flavour Violation [PDF]

, 2002
We consider the supersymmetric seesaw mechanism induced by the exchange of heavy SU(2)_W triplet states, rather than `right-handed' neutrino singlets, to generate neutrino masses. We show that in this scenario the neutrino flavour structure tested at low-

Optimal Coding Schemes for the Three-Receiver AWGN Broadcast Channel with Receiver Message Side Information [PDF]

, 2015
This paper investigates the capacity region of the three-receiver AWGN broadcast channel where the receivers (i) have private-message requests and (ii) may know some of the messages requested by other receivers as side information.

Resonant Trapping of the Moving Groups G18-39 and G21-22 in the Galactic Halo [PDF]

Proceedings of the International Astronomical Union, 2018
AbstractOrbital resonances in the Galactic halo have been studied using the Galactic mass model of Pichardo et al. (2003, 2004), including a Galactic bar. For the two moving groups of the Galactic halo, G18-39 and G21-22 (Silva et al. 2012), the majority of stars in both groups appear trapped in two resonances over the Galactic plane, generated by the ...

Higgs decay into four charged leptons in the presence of dimension-six operators

, 2018
We study the indirect effects of New Physics in the Higgs decay into four charged leptons, using an Effective Field Theory (EFT) approach to Higgs interactions.

Efficiency in the Global Prison System: A Systematic Literature Review and Bibliometric Analysis

Journal of Economic Surveys, EarlyView.
ABSTRACT This study systematizes the international literature on prison system efficiency, highlighting patterns and research gaps through a multidimensional framework. By situating efficiency within broader institutional, social, and rights‐based contexts, it examines how academic research has assessed carceral performance.

Dark States and Interferences in Cascade Transitions of Ultra-Cold Atoms in a Cavity [PDF]

, 2002
We examine the competition among one- and two-photon processes in an ultra-cold, three-level atom undergoing cascade transitions as a result of its interaction with a bimodal cavity. We show parameter domains where two-photon transitions are dominant and

How Intellectual Humility Enhances Affective Well‐Being: Daily Diary Studies on the Mediating Roles of Daily Uplift and Stressor Exposure

Journal of Personality, EarlyView.
ABSTRACT Objective While intellectual humility has gained increasing prominence as a cognitive construct, its implications for affective well‐being remain less understood. Method The present paper draws on 7‐day daily diary datasets (Study 1: Nparticipants = 253, Nobservations = 1721; Study 2: Nparticipants = 485, Nobservations = 3218) to examine how ...

Running of Soft Parameters in Extra Space-Time Dimensions [PDF]

, 1998
The evolution of the parameters including those in the soft supersymmetry-breaking (SSB) sector is studied in the minimal supersymmetric standard model (MSSM) with a certain set of Kaluza-Klein towers which has been recently considered by Dienes et al ...

Propagation method and species drive survival patterns across reef zones in coral seeding on the Great Barrier Reef

Restoration Ecology, EarlyView.
Abstract Introduction Coral reef restoration increasingly relies on scalable methods, yet outcomes vary across species, propagation techniques, and habitats. Coral seeding, where coral propagules are settled on deployment units before outplanting, provides a flexible approach that accommodates both asexual (e.g. microfragments) and sexual (e.g.
