Transverse masses and kinematic constraints
AJ Barr, B Gripaios, CG Lester
Jan 11, 2010
We re-examine the kinematic variable m_T2 and its relatives in the light of recent work by Cheng and Han. Their proof that m_T2 admits an equivalent, but implicit, definition as the `boundary of the region of parent and...
Geometric general solution to the U(1) anomaly equations
Abstract: Costa et al. [Phys. Rev. Lett.123 (2019) 151601] recently gave a general solution to the anomaly equations for n charges in a U(1) gauge theory. ‘Primitive’ solutions of chiral fermion charges were parameterised and it...
Inverse Higgs phenomena as duals of holonomic constraints
B Gripaios, J Tooby-Smith
Feb 07, 2022
The inverse Higgs phenomenon, which plays an important r\^ole in physical systems with Goldstone bosons (such as the phonons in a crystal) involves nonholonomic mechanical constraints. By formulating field theories...
U ( 1 ) B 3 - L 2 explanation of the neutral current B - anomalies
B. C. Allanach
Mar 25, 2021
Abstract: We investigate a speculative short-distance force, proposed to explain discrepancies observed between measurements of certain neutral current decays of B hadrons and their Standard Model predictions. The force derives...

Lorentz- And permutation-invariants of particles
A theorem of Weyl tells us that the Lorentz (and parity) invariant polynomials in the momenta of $n$ particles are generated by the dot products. We extend this result to include the action of an arbitrary permutation group $P...
Global anomalies in the Standard Model(s) and beyond
We analyse global anomalies and related constraints in the Standard Model (SM) and various Beyond the Standard Model (BSM) theories. We begin by considering four distinct, but equally valid, versions of the SM, in which...

Generalized symmetries of topological field theories
Abstract We study generalized symmetries in a simplified arena in which the usual quantum field theories of physics are replaced with topological field...

HD 56414 b
Abstract We report the discovery in TESS data and validation of HD 56414 b (a.k.a. TOI-1228 b), a Neptune-size (R ...
Measuring the Higgs boson mass in dileptonic W-boson decays at hadron colliders
AJ Barr, B Gripaios, CG Lester
Jan 11, 2010
It is expected that hadron collider measurements of the Higgs boson mass using the decay h -> W^+W^-, followed by the leptonic decay of each W-boson, will be performed by fitting the shape of a distribution which is sensitive...
Weighing wimps with kinks at colliders
AJ Barr, B Gripaios, CG Lester
Jan 11, 2010
We consider the application of endpoint techniques to the problem of mass determination for new particles produced at a hadron collider, where these particles decay to an invisible particle of unknown mass and one or...
