Baryogenesis, dark matter, and flavor structure in non-thermal moduli cosmology
Journal of High Energy Physics, 2019 The appearance of scalar/moduli fields in the early universe, as motivated by string theory, naturally leads to non-thermal “moduli cosmology”. Such cosmology provides a consistent framework where the generation of radiation, baryons, and dark matter can

Resource Letter: The Standard Model and Beyond
, 2002 This Resource Letter provides a guide to literature on the Standard Model of elementary particles and possible extensions. In the successful theory of quarks and leptons and their interactions, important questions remain, such as the mechanism of ...

Almost-Commutative Geometries Beyond the Standard Model
, 2005 In [7-9] and [10] the conjecture is presented that almost-commutative geometries, with respect to sensible physical constraints, allow only the standard model of particle physics and electro-strong models as Yang-Mills-Higgs theories. In this publication

Impact of vacuum stability constraints on the phenomenology of supersymmetric models
Journal of High Energy Physics, 2019 We present a fast and efficient method for studying vacuum stability constraints in multi-scalar theories beyond the Standard Model. This method is designed for a reliable use in large scale parameter scans.

, 2018 We discuss the status of the Standard Model (SM): the principles; the Lagrangian; the problems; open questions and the ways beyond. Then we consider possible physics beyond the SM: New symmetries (Gauge, SUSY); New particles (gauge, axion, superpartners); New dimensions (extra, large, compact, etc) or a New Paradigm (strings, branes, gravity).

Simultaneous search for extra light and heavy Higgs bosons via cascade decays
Journal of High Energy Physics, 2017 Models with extended Higgs sectors can contain several additional Higgs states, heavier or lighter than the SM Higgs boson. The couplings of lighter extra states to SM particles can be strongly reduced, leading to small cross sections for their direct ...

Robustness of dark matter constraints and interplay with collider searches for New Physics
Journal of High Energy Physics, 2017 We study the implications of dark matter searches, together with collider constraints, on the phenomenological MSSM with neutralino dark matter and focus on the consequences of the related uncertainties in some detail. We consider, inter alia, the latest

Dark matter casts light on the early Universe
Journal of High Energy Physics, 2018 We show how knowledge of the cold dark matter (CDM) density can be used, in conjunction with measurements of the parameters of a scenario for beyond the Standard Model (BSM) physics, to provide information about the evolution of the Universe before Big ...

Journal of High Energy Physics, 2017 It is well known that the annihilation of Majorana dark matter into fermions is helicity suppressed. Here, we point out that the underlying mechanism is a subtle combination of two distinct effects, and we present a comprehensive analysis of how the ...

The Higgs boson beyond Standard Model.
, 2012 We will review the status of the Higgs boson beyond Standard Model. This proceeding will be focused on the experimental and theoretical status of the Higgs boson in the Composite Higgs models. In particular we will discuss implications on the beyond Standard Model (BSM) Higgs coming from the observed excess at $125$ GeV.
