Neutrino Effects on Atomic Measurements of the Weinberg Angle

Mitrajyoti Ghosh, Yuval Grossman, Chinhsan Sieng +1

We derive a complete expression for the neutrino-mediated quantum force beyond the four-Fermi approximation within the Standard Model. Using this new result, we study the effect of…

Neutrino force at all length scales

Mitrajyoti Ghosh, Yuval Grossman, Chinhsan Sieng +1

The Standard Model predicts a long-range force mediated by a pair of neutrinos, known as ``the neutrino force". It scales as $G_{F}^{2} / r^{5}$ , where $G_{F}$ is the Fermi constant. However…

The neutrino force in neutrino backgrounds: Spin dependence and parity-violating effects

Mitrajyoti Ghosh, Yuval Grossman, Walter Tangarife +2

The neutrino force results from the exchange of a pair of neutrinos. A neutrino background can significantly influence this force. In this work, we present a comprehensive calculat…

Fermion pair radiation from accelerating classical systems

Margarita Gavrilova, Mitrajyoti Ghosh, Yuval Grossman +2

Accelerating classical systems that couple to a fermion-antifermion pair at the microscopic level can radiate pairs of fermions and lose energy in the process. In this work, we der…

A Precision Relation between $Γ (K \to μ^{+} μ^{-}) (t)$ and $B (K_{L} \to μ^{+} μ^{-}) / B (K_{L} \to γ γ)$

Avital Dery, Mitrajyoti Ghosh, Yuval Grossman +2

We find that the phase appearing in the unitarity relation between $B (K_{L} \to μ^{+} μ^{-})$ and $B (K_{L} \to γ γ)$ is equal to the phase shift in the inte…

Neutrino forces in neutrino backgrounds

Mitrajyoti Ghosh, Yuval Grossman, Walter Tangarife +2

The Standard Model predicts a long-range force, proportional to $G_{F}^{2} / r^{5}$ , between fermions due to the exchange of a pair of neutrinos. This quantum force is feeble and has not b…

$K \to μ^{+} μ^{-}$ beyond the standard model

Avital Dery, Mitrajyoti Ghosh

We analyze the New Physics sensitivity of a recently proposed method to measure the CP-violating $B (K_{S} \to μ^{+} μ^{-})_{ℓ = 0}$ decay rate using $K_{S} - K_{L}$ interference. We pre…

$K \to μ^{+} μ^{-}$ as a clean probe of short-distance physics

Avital Dery, Mitrajyoti Ghosh, Yuval Grossman +1

The $K \to μ^{+} μ^{-}$ decay is often considered to be uninformative of fundamental theory parameters since the decay is polluted by long-distance hadronic effects. We demonstrate that,…

SU(3) $_{F}$ Analysis for Beauty Baryon Decays

Avital Dery, Mitrajyoti Ghosh, Yuval Grossman +1

We perform a general SU(3) $_{F}$ analysis of $b \to c c ˉ s (d)$ decays of members of the beauty baryon antitriplet to a member of the light baryon octet and a singlet. Under…

Probing the two-neutrino exchange force using atomic parity violation

Mitrajyoti Ghosh, Yuval Grossman, Walter Tangarife

The exchange of two neutrinos at one loop leads to a long-range parity-violating force between fermions. We explore the two-neutrino force in the backdrop of atomic physics. We poi…
