What’s Decidable about Weak Memory Models?
, 2012 We investigate the decidability of the state reachability problem in finite-state programs running under weak memory models. In [3], we have shown that this problem is decidable for TSO and its extension with the write-to-write order relaxation, but ...

Complete UV resonances of the dimension-8 SMEFT operators
Journal of High Energy PhysicsThe effective field theory approach parameterizes the low energy behaviors of all possible ultraviolet (UV) theories in a systematic way. One of the most important tasks is thus to find the connection between the effective operators and their UV origins.

Searches for BSM Physics in Rare B-Decays in ATLAS
, 2014 Beyond Standard Model (BSM) Physics can be searched for indirectly in processes strongly suppressed in the Standard Model, e.g. in flavor-changing neutral-current processes.

BSM searches (SUSY and Exotic) from ATLAS
, 2015 Searches for new physics beyond the Standard Model (SM) at the LHC are mainly driven by two approaches: a signature-based search where one looks for a deviation from the SM prediction in event yield or kinematic properties, and a more theory-oriented ...

Measuring the polarization of boosted, hadronic W bosons with jet substructure observables
Journal of High Energy PhysicsIn this work, we present a new technique to measure the longitudinal and transverse polarization fractions of hadronic decays of boosted W bosons. We introduce a new jet substructure observable denoted as p θ , which is a proxy constructed purely out of ...

Systematic decomposition of dimension-11 short-range neutrinoless double beta decay operators
Journal of High Energy PhysicsNeutrinoless double beta decay (0νββ) may receive sizable contributions from short-range physics beyond the Standard Model. We present a systematic classification of all tree-level ultraviolet completions of the dimension-11 short-range 0νββ decay ...

CP violation in Σ+ → pℓ + ℓ − within the standard model and beyond
Journal of High Energy PhysicsThe LHCb collaboration has recently observed the rare hyperon decay Σ+ → pμ + μ −. It can also measure the corresponding antihyperon channel with comparable precision and is thus in a position to extract information on CP violation in this mode ...

General form of effective operators from hidden sectors
Journal of High Energy PhysicsWe perform a model-independent analysis of the dimension-six terms that are generated in the low energy effective theory when a hidden sector that communicates with the Standard Model (SM) through a specific portal operator is integrated out.

Weak Scale Effects in Growth Models [PDF]
, 2005 Growth models of the second generation type, e.g. the Jones (1995) or Young (1998) model, all exhibit a so called weak scale effect in per capita production, i.e. larger economies should have a higher per capita production than smaller economies. However,

Quantum detection of new physics in top-quark pair production at the LHC
Journal of High Energy PhysicsThe recent observation of entanglement between top and anti-top quarks at the LHC opens the way to interpreting collider data with quantum information tools. In this work we investigate the relevance of quantum observables in searches of new physics.
