(a) Charge is conserved.

(b) Baryon number not conserved.

(d) Spin angular momentum not conserved.

(e) Strangeness conserved.

(f) Muon lepton number conserved.

Step 1: Conservation Law

A principle that states that a certain physical property does not charge in the course of time within an isolated physical system. or

The law states that the total energy of an isolated system does not change.

Step 2: Charge

a. Solution.

$P + \bar{P} \to λ ° + \sum_{}^{+} + e^{-} c h a r g e 1 - 1 0 + 1 - 1$

Hence, Charge is conserved.

Step 3: Baryon number

b. Solution.

$P + \bar{P} \to λ ° + \sum_{}^{+} + e^{-} B a r y o n n u m b e r 1 - 1 1 1 0$

Hence, the Baryon number is not conserved.

Step 4:electron lepton number

c. Solution. $P + \bar{P} \to λ ° + \sum_{}^{+} + e^{-} e l e c t r o n l e p t o n n u m b e r 0 0 0 0 1$

Hence, the Electron lepton number is not conserved.

Step 5:spin angular momentum

d. Solution.

$P + \bar{P} \to λ ° + \sum_{}^{+} + e^{-} s p i n \frac{1}{2} \frac{1}{2} \frac{1}{2} \frac{1}{2} \frac{1}{2}$

Hence, Spin angular momentum is not conserved.

Step 6:Strangeness

e. Solution.

$P + \bar{P} \to λ ° + \sum_{}^{+} + e^{-} S t r a n g e n e s s 0 0 - 1 1 0$

Hence, Strangeness is conserved.

Step 7:muon lepton number

f. Solution.

$P + \bar{P} \to λ ° + \sum_{}^{+} + e^{-} M o u n L a p t o n N u m b e r 0 0 0 0 0$

For all particles moun lepton number is zero.

This process does conserve moun lepton number.
