BPS solutions for generalised Wess-Zumino models and their applications (2019)
Journal Article
Abel, S., Bonnefoy, Q., & Chowdhury, D. (2019). BPS solutions for generalised Wess-Zumino models and their applications. Journal of High Energy Physics, 2019(10), Article 242. https://doi.org/10.1007/jhep10%282019%29242

We present BPS solutions to a general class of Wess-Zumino models which ex- tend previous results in the literature. We discuss their relation to amplitudes on threshold, and their application to scalar domain walls in Supersymmetric QCD. We also fin...

Staccato radiation from the decay of large amplitude oscillons (2020)
Journal Article
Dorey, P., Romanczukiewicz, T., & Shnir, Y. (2020). Staccato radiation from the decay of large amplitude oscillons. Physics Letters B, 806, Article 135497. https://doi.org/10.1016/j.physletb.2020.135497

We study the decay of large amplitude, almost periodic breather-like states in a deformed sine-Gordon model in one spatial dimension. We discover that these objects decay in a staggered fashion via a series of transitions, during which higher harmoni...

Relic density of dark matter in the inert doublet model beyond leading order: The heavy mass case (2019)
Journal Article
Banerjee, S., Boudjema, F., Chakrabarty, N., Chalons, G., & Sun, H. (2019). Relic density of dark matter in the inert doublet model beyond leading order: The heavy mass case. Physical Review D, 100(9), Article 095024. https://doi.org/10.1103/physrevd.100.095024

A full renormalization of the inert doublet model is presented and exploited for a precise calculation of the relic density of dark matter (DM) at one-loop. In this first paper, we study the case of a DM candidate with mDM ∼ 500 GeV. In this regime,...

It is a common belief that the last missing piece of the Standard Model of particles physics was found with the discovery of the Higgs boson at the Large Hadron Collider. However, there remains a major prediction of quantum tunnelling processes media... Read More about Large Effects from Small QCD Instantons: Making Soft Bombs at Hadron Colliders.

Novel B-decay signatures of light scalars at high energy facilities (2019)
Journal Article

We study the phenomenology of light scalars of masses m1 and m2 coupling to heavy flavor-violating vector bosons of mass mV. For m1;2 ≲ few GeV, this scenario triggers the rare B meson decays B0s → 3μþ3μ−, B0 → 3μþ3μ−, Bþ → Kþ3μþ3μ−, and B0s → K03μþ3...

We consider constraints on the S-matrix of any gapped, Lorentz invariant quantum field theory in 3+1 dimensions due to crossing symmetry, analyticity and unitarity. We extremize cubic couplings, quartic couplings and scattering lengths relevant for t... Read More about The S-matrix bootstrap. Part III: higher dimensional amplitudes.

We compute the next-to-next-to-leading order (NNLO) QCD corrections to event shape distributions and their mean values in deep inelastic lepton–nucleon scattering.

Cardiac tissue and the Belousov-Zhabotinsky reaction provide two notable examples of excitable media that support scroll waves, in which a filament core is the source of spiral waves of excitation. Here we consider a novel topological configuration i... Read More about Threaded Rings that Swim in Excitable Media.

Starting from 6D superconformal field theories (SCFTs) realized via F-theory, we show how reduction on a circle leads to a uniform perspective on the phase structure of the resulting 5D theories, and their possible conformal fixed points. Using the c... Read More about 6D SCFTs and phases of 5D theories.

Heavy neutrinos with additional interactions have recently been proposed as an explanation to the MiniBooNE excess. These scenarios often rely on marginally boosted particles to explain the excess angular spectrum, thus predicting large rates at high...

We examine the effect of large extra dimensions on vacuum decay in the Randall– Sundrum (RS) braneworld paradigm. We assume the scalar field is confined to the brane, and compute the probability for forming an “anti-de Sitter” (AdS) bubble inside a c... Read More about Higgs vacuum decay in a braneworld.
