Status of LHC Searches for SUSY without R‐Parity
Advances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015 In this contribution we briefly review the status of current searches for supersymmetry at the Large Hadron Collider, focusing especially on viable sub‐TeV colored superpartners which can appear in nonstandard scenarios. The presented material covers mostly signals that do not crucially rely on the presence of large missing transverse momentum, with ...

Hunting and identifying coloured resonances in four top events with machine learning
Journal of High Energy PhysicsWe study prospects to search for pair or singly produced colour octet or colour sextet scalars which decay into two top quarks at the LHC. We focus on the same-sign lepton final state.

Electroweak ALP searches at a muon collider
Journal of High Energy Physics, 2022 A high-energy muon collider with center-of-mass energy around and above 10 TeV is also a vector boson fusion (VBF) machine, due to the significant virtual electroweak (EW) gauge boson content of high-energy muon beams.

Top Quark Flavor Changing Couplings at a Muon Collider
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.There is growing interest in the development of a muon collider that would make it possible to produce lepton collisions at energies of several TeV. Among others, there can be significant contributions to electroweak gauge boson, Higgs boson, and top quark physics.

Exploring New Models in All Detail with SARAH
Advances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015 I give an overview about the features the Mathematica package SARAH provides to study new models. In general, SARAH can handle a wide range of models beyond the MSSM coming with additional chiral superfields, extra gauge groups, or distinctive features like Dirac gaugino masses.

Coloured spin-1 states in composite Higgs models
Journal of High Energy PhysicsStrong dynamics for composite Higgs models predict spin-1 resonances which are expected to be in the same mass range as the usually considered top-partners.

Probing axion-like particles coupling to gluons at the LHC
Journal of High Energy Physics, 2022 Assuming ALPs couple to gluons only, they can be produced via the pp → aj process and decay into two jets at the LHC. When the coupling parameter, C G ~ $$ {C}_{\overset{\sim }{G}} $$ /f a , is small, the lifetime of ALPs can be long enough leading to ...

Renormalization of the SMEFT to dimension eight: Fermionic interactions I
Journal of High Energy PhysicsThis is the third of a series of works [1, 2] aimed at renormalizing the Standard Model effective field theory at one loop and to order 1/Λ4, with Λ being the new physics cut-off.

An updated view on the ATOMKI nuclear anomalies
Journal of High Energy Physics, 2023 In view of the latest experimental results recently released by the ATOMKI collaboration, we critically re-examine the possible theoretical interpretation of the observed anomalies in terms of a new BSM boson X with mass ~ 17 MeV. To this end we employ a

Electroweak Symmetry Breaking and BSM Physics (A Review) [PDF]
, 2008 In this talk, I shall first discuss the standard model Higgs mechanism and then highlight some of its deficiencies making a case for the need to go beyond the standard model (BSM). The BSM tour will be guided by symmetry arguments.
