Radiative corrections for the decay $Σ^{0} \to Λ e^{+} e^{-}$

Tomáš Husek, Stefan Leupold

Electromagnetic form factors serve to explore the intrinsic structure of nucleons and their strangeness partners. With electron scattering at low energies the electromagnetic momen…

The electromagnetic form factors of the transition from the spin-3/2 Sigma to the Lambda hyperon

Olov Junker, Stefan Leupold, Elisabetta Perotti +1

The three electromagnetic form factors for the transition from a 3/2+ Sigma* hyperon to the ground-state Lambda hyperon are studied. At low energies, combinations of the transition…

Low-energy axial-vector transitions from decuplet to octet baryons

Måns Holmberg, Stefan Leupold

Axial-vector transitions of decuplet to octet baryons are parametrized at low energies guided by a complete and minimal chiral Lagrangian up to next-to-leading order. It is pointed…

Sequential hyperon decays in the reaction $e^{+} e^{-} \to Σ^{0} Σ ˉ^{0}$

Göran Fäldt, Karin Schönning

We report on a study of the sequential hyperon decay $Σ^{0} \to Λ γ; Λ \to p π^{-}$ and its corresponding anti-hyperon decay. We derive a multi-dimentional and model-indepen…

CP symmetry tests in the cascade-anticascade decay of charmonium

Patrik Adlarson, Andrzej Kupsc

We analyze joint angular distributions of a charmonium decay to the $Ξ Ξ ˉ$ pair using the $Ξ \to Λ π \to p π^{-} π$ weak decay chain for the cascade and the charge conjugated mode for th…

Hunting scalar leptoquarks with boosted tops and light leptons

Kushagra Chandak, Tanumoy Mandal, Subhadip Mitra

The LHC search strategies for leptoquarks that couple dominantly to a top quark are different than for the ones that couple mostly to the light quarks. We consider charge $1/3$ ($ϕ…

Signatures of vector-like top partners decaying into new neutral scalar or pseudoscalar bosons

Rachid Benbrik, Elin Bergeaas Kuutmann, Diogo Buarque Franzosi +9

We explore the phenomenology of models containing one Vector-Like Quark (VLQ), $t^{'}$ , which can decay into the Standard Model (SM) top quark, $t$ , and a new spin-0 neutral boson, $S…

Varying gauge couplings and collider phenomenology

Ulf Danielsson, Rikard Enberg, Gunnar Ingelman +1

In this paper we investigate a natural extension of the Standard Model that involves varying coupling constants. This is a general expectation in any fundamental theory such as str…

Probing the inert doublet model using jet substructure with a multivariate analysis

Akanksha Bhardwaj, Partha Konar, Tanumoy Mandal +1

We explore the challenging but phenomenologically interesting hierarchical mass spectrum of the Inert Doublet Model where relatively light dark matter along with much heavier scala…

Chiral Estimate of QCD Pseudocritical Line

K. Zarembo

Relatively low crossover temperature suggests that chiral symmetry restoration in QCD may well be described within the low-energy effective theory. The shape of the pseudocritical…

Addressing the $R_{D^{(*)}}$ anomalies with an $S_{1}$ leptoquark from $SO (10)$ grand unification

Ufuk Aydemir, Tanumoy Mandal, Subhadip Mitra

Motivated by the $R_{D^{(*)}}$ anomalies, we investigate an $SO (10)$ grand unification scenario where a charge $- 1/3$ scalar leptoquark ( $S_{1}$ ) remains as the only new phy…
