    Undergrad Is simulation considered a type of quantitative analysis?

    Hello, I've been asked to talk about a time where I have used quantitative analysis. I once used simulation of the solar system to find out more about things like close approaches, and Gladmans criteria I was wondering if simulation is considered a quantitative method of analysis and if the...

    Undergrad Hermitian operators, matrices and basis

    Got it, thank you!

    Undergrad Hermitian operators, matrices and basis

    Hello, I would just like some help clearing up some pretty basic things about hermitian operators and matricies. I am aware that operators can be represented by matricies. And I think I am right in saying that depending on the basis used the matrices will look different, but all our valid...

    Undergrad Dark Matter Decoupling from Plasma

    Hello, I have been reading about how Dark Matter particles might possibly be made up of the lightest sterile right handed neutrino. I was wondering, why exactly does the dark matter particle have to decouple from the plasma when it is formed?

    Undergrad Difference of resonant and non-resonant neutrino oscillation

    Hello Just wondering what the difference is between resonant and non-resonant neutrino oscillations. Are resonant neutrino oscillations called Mikheyev-Smirnov-Wolfenstein? Thank you

    Undergrad When is a right handed neutrino a heavy neutral lepton(HNL)?

    Hello, I was just wondering when is a right handed neutrino a heavy neutral lepton? I know that RH neutrinos show up in a number of extension to the standard model, for example the neutrino minimal standard model (vMSM) and Left-right symmetric extensions. Ive heard them being referred to as...

    Undergrad Neutrino Mass, Baryogenesis, Dark Matter (Beyond the SM)

    Hello, So I am aware that neutrino masses, Baryogengesis/Baryon Asymmetry, and Dark matter cannot be explained by the standard model. However each can be explained by right handed neutrinos. I know that right handed neutrinos show up in many extensions to the standard model, e.g. vMSM (where...

    Undergrad Right Handed Neutrinos/Heavy Neutral Leptons

    When are right handed neutrinos considered to be heavy neutral leptons (HNL). For instance are the RH neutrinos in the vMSM HNL? Are the RH neutrinos in the Left-Right extensions of the standard model HNL?Thank you

    Undergrad Neutrino Oscillations and Mass

    Hello Just wondering, would neutrino oscillations occur is the three standard model neutrinos were the same mass? or are different masses needed in order to have different phases differences, as the phases differences are why the oscillations occur?Also why do neutrino oscillations prove that...

    Undergrad Seesaw Mechanism of vMSM and Left Right Symmetric Extension

    I know the seesaw mechanism is a model used to explain both neutrinos having mass and why their dirac mass/yukawa coupling is so much smaller than for the other fermions. The seesaw mechanism needs the right handed neutrino to exist. How does the seesaw mechanism for the vMSM differ from that...

    Undergrad Standard Model SU(2) singlets and doublets

    I know that for SU(2), weak interaction, in the standard model the right handed leptons are singlets, (and right handed neutrinos don't exist). For right handed quarks are they singlets or doublets in the standard model. So is it (u d)R or is it just u(R) and d(R)

    Undergrad Left Right Symmetric Extension of SM and vMSM

    So they are two different extensions?? Do the right handed neutrinos only get their mass from the seesaw mechanism in the vMSM?? How are they given mass in the L-R symmetric extension? Do you have any suggestions where I may be able to read up more about these two extensions? Thank you

    Undergrad Left Right Symmetric Extension of SM and vMSM

    Hello. Im trying to learn more about different extensions of the standard model. Are the Left Right Symmetric Extension of the Standard model and the Neutrino Minimal Standard Model different extensions? I know both add 3 right handed neutrinos. Do these neutrinos differ in any way, also are...

    Undergrad Do Neutrinos Need to be Their Own Antiparticle for Majorana Masses to Exist?

    Oh right, perfect. Thank you very much!

    Undergrad Do Neutrinos Need to be Their Own Antiparticle for Majorana Masses to Exist?

    thank you! But I thought the Majorana masses didn't conserve lepton number? As it allows coupling of particle and antiparticle pairs??
